Inverting dual-supply to single-supply amplifier circuit

CIRCUIT060066

Overview

This inverting dual-supply to single-supply amplifier translates a ±10-V signal to a 0-V to 5-V signal for use with an ADC. Levels can easily be adjusted using the given equations. The buffer can be replaced with other ±15-V configurations to accommodate the desired input signal, as long as the output of the first stage is low impedance.
Features
  • Input: Vi = -10 V to 10 V
  • Output: Vo = 0.2 V to 4.8 V
  • Supply:
    • Vcc = 15 V
    • Vee = -15 V
    • Vdd = 5 V
    • Vref = 4.096 V
