Non-inverting op amp with non-inverting positive reference voltage circuit

CIRCUIT060064

Overview

This design uses a non-inverting amplifier with a non-inverting positive reference to translate an input signal of –1 V to 3 V to an output voltage of 0.05 V to 4.95 V. This circuit can be used to translate a sensor output voltage with a positive slope and negative offset to a usable ADC input voltage range.
Features
  • Input: Vi = -1 V to 3 V
  • Output: Vo = 0.05 V to 4.95 V
  • Supply:
    • Vcc = 5 V
    • Vee = 0 V
    • Vref = 2.5 V
General-purpose op amps
