Inverting op amp with non-inverting positive reference voltage circuit
CIRCUIT060019
Overview
This design uses an inverting amplifier with a non-inverting positive reference voltage to translate an input signal of –1 V to 2 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.
