Definitions
Gain
Gain is defined as the slope of the best-fit line of differen-
tial output voltage (V

offset error adjusted out.
Nonlinearity
Nonlinearity is defined as half of the peak-to-peak output
deviation from the best-fit gain line, expressed as a per-
centage of the full-scale differential output voltage.

Common Mode Transient Immunity, CMTI, also known as Com-
mon Mode Rejection
CMTI is tested by applying an exponentially rising/falling
voltage step on pin 4 (GND1) with respect to pin 5 (GND2).
The rise time of the test waveform is set to approximately
50 ns. The amplitude of the step is adjusted until the dif-
ferential output (V
mV deviation from the average output voltage for more
than 1Ps. The ACPL-C79B/C79A/C790 will continue to
function if more than 10 kV/μs common mode slopes are
applied, as long as the breakdown voltage limitations are
observed.
Power Supply Rejection, PSR
PSR is the ratio of differential amplitude of the ripple
outputs over power supply ripple voltage, referred to the
input, expressed in dB.
