CIRCUIT060017

Dual-supply, discrete, programmable gain amplifier circuit

CIRCUIT060017

Overview

This circuit provides programmable, non-inverting gains ranging from 6 dB (2 V/V) to 60 dB (1000 V/V) using a variable input resistance. The design maintains the same cutoff frequency over the gain range.
Features
  • Dual +/- 2.5-V supply
  • Input: +/- 1.25 V
  • Output: +/-2.4 V
  • Bandwidth: 7 kHz
  • Gain: 2 V/V to 1000 V/V
