Band pass filtered inverting attenuator circuit

CIRCUIT060050

Overview

This tunable band-pass attenuator reduces signal level by –40 dB over the frequency range from 10 Hz to 100 kHz. It also allows for independent control of the DC output level. For this design, the pole frequencies were selected outside the pass band to minimize attenuation within the specified bandwidth range.
Features
  • Input: Vi = 100 mV to 50 V
  • Output: Vo = 1 mV to 500 mV
  • Supply:
    • Vcc = 15 V
    • Vee = -15V
    • Vref = 0V
