-12 dB to +60 dB

D83S Series

Programmable Amplifier

Features/Benefits:

• Full power bandwidth to 100 kHz for wide dynamic

range applications

• Compact 1.8" x 0.8" x 0.3" (32 pin DIP) size minimizes

board space requirements

• Serial

interface

and

software

protocol

allowing

operation on a simple three wire bus.

• Data out line allows data verification and cascading of

multiple amplifiers over the same serial interface.

• Plug-in ready-to-use, reducing engineering design and

manufacturing time.

Applications

• Data acquisition

• Test equipment

• Remote instrumentation systems

• Ground loop elimination in remote measurements

• Improvements in system dynamic range and resolution

• Telemetry

• Process control

• Digitally controlled auto ranging systems

• Medical, Scientific & engineering research

Description

The D83S Series programmable amplifiers are digitally

controlled gain modules that were designed for condition-

ing DC-coupled wide-band signals (AC coupled-optional).

They are programmable from -12 dB to +60 dB in 6 dB

steps with an 8-bit serial data stream for gain selection

using clock, data and strobe inputs.

Other standard performance features include differential

input, single ended output, 5V interface logic, and low

noise and distortion, making this plug-in ready-to-use

amplifier ideal for many signal conditioning applications.

Available options include AC coupled input and/or differ-

ential output.
