Inverting op amp with inverting positive reference voltage circuit
CIRCUIT060062
Overview
This design uses an inverting amplifier with an inverting positive reference to translate an input signal of –5 V to –1 V to an output voltage of 3.3 V to 0.05 V. This circuit can be used to translate a negative sensor output voltage to a usable ADC input voltage range.
Features
- Input: Vi = -5 V to -1 V
- Output: Vo = 0.05 V to 3.3 V
- Supply:
- Vcc = 5 V
- Vee = 0 V
- Vref = 5 V
