111-352

These devices have been designed as complete laser diode systems for OEM use and although their output powers have been set in accordance with BS(EN)60825, they are not certified lasers as defined in the specification. When incorporated in a piece of equipment, it may be necessary for additional safety features to be added before equipment complies fully with the standard. BS(EN)60825 is essential reading before using any of these products. Additional information can also be found in the latest RS Data Sheet.

Absolute maximum ratings

Laser safety

All laser devices produce beams of intense monochromatic light which can present potential biological hazards. These hazards depend on a number of factors including the wavelength, the power or energy of the beam and the emission duration. The eye is the most vulnerable organ as it will tend to focus light from the laser on to the retina, thereby increasing the energy density many times. RS stock no. 111-352 emits an invisible beam of light and requires the greatest care, protective goggles should be worn when using this product. More information can be found in the latest RS Data Sheet. Laser safety is covered by BS(EN)60825 which is essential reading for all laser users.

Description

These laser modules consist of a laser diode, lens and driver circuit housed in a metal case. Electrical connections are made via flying leads. The lens is a single element of high refractive index glass which produces a high quality collimated beam over a long distance. Its position can be adjusted to bring the beam to a focused spot using the special key provided. The standard collimating lens may be replaced by a line generating lens which produces a fan shaped beam that can be focused to a fine, straight line.

Power supplies and earthing

Laser modules which operate from a negative voltage can be run from an unregulated supply within the range of -8 to -12 volts. By operating at the lower (-8 volts) end of the power supply range, less heat will be dissipated within the device and hence the expected life will increase. Laser modules which operate from a positive voltage may only be run from a supply which has been regulated to at least 5%, within the limits specified.

It is advisable for any floating power supplies to have the ‘0’ volts connection (and if used, the heatsink) taken to ground. If this is not done, then in electrically noisy environments, the power supply leads can act as aerials. Under these conditions any noise picked up can damage the laser module. If a heatsink is not used, then the barrel of the laser module should be grounded.

For all laser modules, the case is isolated from the supply voltages.

TTL disable

This feature is only available on laser modules which operate from a negative supply voltage.

An input of between +4 and +7 volts applied to the TTL disable input will turn the laser ‘off’ and an input of 0 volts will turn it ‘on’. If it is not in use, it may be left floating. The laser may be pulsed ‘on’ and ‘off’ using this input to a frequency of at least 10Hz.

Heat sinking

When operating above their minimum supply voltages and/or at elevated temperatures above 30°C ambient, heat sinking must be used. If the case temperature of the embedded laser diode should exceed its maximum specification, premature or even catastrophic failure may occur.

The latest RS Data Sheet gives full details on how to determine the optimum heat sink requirements for the particular model and operating conditions.

LM1876 Overture

™

Audio Power Amplifier Series

Dual 20W Audio Power Amplifier with Mute and Standby

Modes

General Description

The LM1876 is a stereo audio amplifier capable of delivering typically 20W per channel of continuous average output power into a 4Ω or 8Ω load with less than 0.1% THD+N. Each amplifier has an independent smooth transition fade-in/out mute and a power conserving standby mode which can be controlled by external logic.

The performance of the LM1876, utilizing its Self Peak In-stantaneous Temperature (˚Ke) (SPiKe™) protection cir-cuitry, places it in a class above discrete and hybrid amplifi-ers by providing an inherently, dynamically protected Safe Operating Area (SOA). SPiKe protection means that these parts are safeguarded at the output against overvoltage, undervoltage, overloads, including thermal runaway and in-stantaneous temperature peaks.

General Description

The MAX541/MAX542 are serial-input, voltage-output, 16-bit digital-to-analog converters (DACs) that operate from a single +5V supply. They provide 16-bit perfor-mance (±1LSB INL and DNL) over temperature without any adjustments. The DAC output is unbuffered, result-ing in a low supply current of 0.3mA and a low offset error of 1LSB.

The DAC output range is 0V to VREF. For bipolar opera-tion, matched scaling resistors are provided in the MAX542 for use with an external precision op amp (such as the MAX400), generating a ±VREFoutput swing. The MAX542 also includes Kelvin-sense con-nections for the reference and analog ground pins to reduce layout sensitivity.

A 16-bit serial word is used to load data into the DAC latch. The 10MHz, 3-wire serial interface is compatible with SPI™/QSPI™/MICROWIRE™, and it also interfaces directly with optocouplers for applications requiring isola-tion. A power-on reset circuit clears the DAC output to 0V (unipolar mode) when power is initially applied. The MAX541 is available in 8-pin plastic DIP and SO packages. The MAX542 is available in 14-pin plastic DIP and SO packages.

FT245R USB FIFO I.C.

Incorporating FTDIChip-ID™ Security Dongle

The FT245R is the latest device to be added to FTDI’s range of USB FIFO interface Integrated Circuit Devices.

The FT245R is a USB to parallel FIFO interface, with the new FTDIChip-ID™ security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to parallel designs using the FT245R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. The FT245R adds a new function compared with its predecessors, effectively making it a “2-in-1” chip for some application areas. A unique number (the FTDIChip-ID™) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied.

The FT245R is available in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages.

Version 2.01

Introduction to FTDI’s D2XX 2.0

Driver Technology

FTDI’s “D2XX Direct Drivers” for Windows offer an alternative solution to our VCP drivers which allows application software to interface with FT232 USB UART and FT245 USB FIFO devices using a DLL instead of a Virtual Com Port. The architecture of the D2XX drivers consists of a Windows WDM driver that communicates with the device via the Windows USB Stack and a DLL which interfaces the Application Software (written in VC++, C++ Builder, Delphi, VB etc.) to the WDM driver. An INF installation file, Uninstaller program and D2XX Programmers Guide complete the package.

The new version of the D2XX drivers contains many enhanced features and has been divided into four groups for clarity. The Classic Interface Section documents the original D2XX functions that are retained in this new release. The Classic Interface provides a simple, easy to use, set of functions to access these FTDI USB devices. New sections are “The EEPROM Interface” which allows application software to read / program the various fields in the 93C46 EEPROM including a user defined area which can be used for application specific purposes; “The FT232BM / FT245BM Enhancements” which allow control of the additional

features in our 2nd _{generation devices, and the “FT-Win32 API”}

which is a more sophisticated alternative to the Classic Interface – our equivalent to the native Win 32 API calls that are used to control a legacy serial port. Using the FT-Win32 API, existing Windows legacy Comms applications can easily be converted to use the D2XX interface simply by replacing the standard Win32 API calls with the equivalent FT-Win32 API calls.

Please Note – the Classic Interface and the FT-Win32 API interface are alternatives. Developers should choose one or the other – the two sets of functions should not be mixed.

Piezoelectric motor structures

Abstract

A piezoelectric motor, bases on utilization of the reverse piezoelectric effect for continuous conversion of

electric power into mechanical energy of rotation of the rotor. The piezoelectric motor includes a rotor and

a stator, at least one of them incorporating a vibrator of mechanical oscillation, having a piezoelectric

device connected to a voltage source and converting electric power into mechanical vibrations. The

piezoelectric motor contains no windings and provides considerable driving torques, owing to the stator

and rotor being urged against each other. The structure of the piezoelectric motor is determined by the

arrangement of the piezoelectric device in the rotor and stator, the type of oscillation being excited, the

shape of the piezoelectric device, the arrangement of its electrodes, their shape and electrical connection,

as well as by the polarization of the piezoelectric material. Various combinations of these features offer a

great variety of structures and designs of the piezoelectric motors, the piezoelectric motor being supplied

from a voltage source with supersonic frequency.

Piezoelectrically driven torsional vibration motor

Abstract

The vibration motor of the invention comprises a concentrator of torsional vibrations including at least two

stages. The first one of the stages takes up vibrations from a piezoelectric cell while the second stage

contacts a rotor. The concentrator is provided with means for transforming piezoelectric cell vibrations

into torsional ones, said means being fashioned as rods provided on the side surface of the first stage. The

rods are located in a plane normal to the concentrator axis and inclined each at an acute angle to a tangent

at the point where the rod is attached to the line of intersection of the side surface of the first stage with

said plane. The rods serve as resonators of longitudinal vibrations propagating therein.
