D86 Series
Differential Input
-12 dB to +60 dB Buffer Amplifier
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.
