AC-coupled inverting amplifier circuit

CIRCUIT060048

Overview

This circuit amplifies an AC signal and shifts the output signal so that it is centered at half the power-supply voltage. Note that the input signal has zero DC offset so it swings above and below ground. The key benefit of this circuit is that it accepts signals that swing below ground even though the amplifier does not have a negative power supply.

Features
  • Input: Vi = -240 mV tto 240 mV
  • Output: Vo = 0.1 V to 4.9 V
  • Supply
    • Vcc = 5 V
    • Vee = 0 V
    • Vref = 5 V
