Description

The D83P Series programmable amplifiers are digitally controlled gain modules that were designed for conditioning DC-coupled wide-band signals (AC coupled - optional). They are programmable from -12 dB to +60 dB in 6 dB steps with an 4-bit parallel word.

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 differential 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
  • Parrallel 4-bit word for easy gain control.
  • 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
 


Gain Amplifier
Digital Programming & Control

The D83P programs via a four terminal parallel data interface over a gain range from 0.25 (~ -12dB) to 1024 (~+60dB).

Two stages of programmable gain/attenuation are used to optimize the D-C offset and gain bandwidth performance.
