3. Electrical characteristics

This section describes the electrical characteristics specific to op-amps.

When an op-amp is used as an amplifier, the common-mode input voltage range indicates the input voltage range in which it operates properly. When an op-amp is used to amplify a tiny signal from a sensor or other device, what the sensor resolution is to a sensor is what the input offset voltage or the common-mode input signal rejection ratio (CMRR) is to an op-amp. The minimum resolution is determined by the amount of noise.

This section describes the following:

1. Input offset voltage, V_IO
2. Common-mode input voltage range (CMV_IN), common-mode input signal rejection ratio (CMRR)
3. Op-amp noise
4. Noise gain and signal gain
