y Common-mode input signal rejection ratio (CMRR)
The common-mode input signal rejection ratio,
CMRR, can be calculated by the following
expression, with the offset voltage (V_IO) defined as
V_IN1 minus V_IN2 at which V_OUT is changed by changing
VOUT
V_IN1.
Measurement conditions:
When V_IN2 = V_CMR (max.): V_IO = V_IO1
When V_IN2 = V_CMR (min.): V_IO = V_IO2

y Common-mode input voltage range (V_CMR)
The common-mode input voltage range is the range
of V_IN2 within which V_OUT satisfies the common mode
input signal rejection ratio specification.
