D83S Series
-12 dB to +60 dB
Programmable Amplifier
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.
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
