Inverting amplifier with T-network feedback circuit



This design inverts the input signal, VIN, and applies a signal gain of 1000 V/V or 60 dB. The inverting amplifier with T-feedback network can be used to obtain a high gain without a small value for R4 or very large values for the feedback resistors.
  • Dual +/- 5-V supply
  • Input: +/- 2.5 mV
  • Output: +/- 2.5 V
  • Bandwidth: 5 kHz
  • Gain: 1000 V/V
