Since it can’t influence the + terminal, it will drive the voltage through the resistor network to ensure the – terminal is at 0V. Continue reading “Circuit VR: Even More Op Amps” → Posted in Hackaday Columns, Skills, SliderTagged amplifier, common mode noise, differential amplifier,...
where with Vocm I noted the common-mode voltage at the differential amplifier output. Since the signal of interest is the difference V1-V2, the common-mode error at the differential amplifier output is Vocm. After calculations, and using (4), Vocm becomes ...
Differential Amplifiers Introduction:One of the most useful circuits in the field of instrumentation is the differential amplifier. This device is designed to amplify the difference between two voltages and to provide a ground referenced output voltage. Operational amplifiers are frequently used in this ...

The VCM terminal sets the common-mode voltage of the differential output. This is particularly useful when driving single-supply ADCs, as the common-mode output of the circuit can be set to midsupply. The gain from VCM to the output is 1. Connect this node to ground if common-mode adjust...
