Description

The D86 Series are differential input, single-ended output buffer amplifiers for conditioning DC-coupled wide-band signals. (AC coupled-optional). Components are selected and configured to provide full signal bandwidth to 100 kHz in all models.

These amplifiers are particularly useful to scale sensor outputs to signal levels that optimize signal-to-noise ratios prior to their input to FDI active filter modules. Available in 13 fixed gain models from -12 dB to +60 dB with options that 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
  • 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
  • Medical, Scientific & engineering research
