2.10 Common-mode rejection ratio (CMRR)

Signifies the ratio of fluctuation of the input offset voltage when the in-phase input voltage is changed (DC fluctuation).

CMRR = (change in input common-mode voltage) / (input offset fluctuation)

2.11 Power supply rejection ratio (PSRR)

Denotes the ratio of fluctuation of the input offset voltage when supply voltage is changed (DC fluctuation).

SVR = (change in power supply voltage) / (input offset fluctuation)

2.12 Output source current/ output sink current (IOH/IOL)

The maximum current that can be output under specific output conditions, it is divided into output source current and

output sink current. The output source current indicates the current flowing out of the IC, and the output sink current

the current flowing into the IC.

2.13 Channel separation (CS)

Expresses the amount of fluctuation of the input offset voltage or output voltage with respect to the change in the

output voltage of a driven channel.

2.14 Slew rate (SR)

Indicates the time fluctuation ratio of the output voltage when an input step signal is supplied.

2.15 Gain bandwidth product (GBW)

The product of the specified signal frequency and the gain of the op-amp at such frequency, it gives the approximate

value of the frequency where the gain of the op-amp is 1 (maximum frequency, and unity gain frequency).
