Common-Mode Rejection Ratio (CMRR)

CMRR is the ratio of the power in the µModule output at the

frequency, f, to the power of a 1.3 V p-p sine wave applied to the

input common-mode voltage of frequency, f.

CMRR (dB) = 10log(PµModule_IN/PµModule_OUT)

where:

PµModule_IN is the common-mode power at the frequency, f, applied

to the inputs.

PµModule_OUT is the power at the frequency, f, in the µModule output.

Power Supply Rejection Ratio (PSRR)

PSRR is the ratio of the power in the µModule output at the

frequency, f, to the power of a 500 mV p-p sine wave applied to the

VDD and VS+ supply voltage centered at 5 V and 100 mV p-p for a

VS− supply voltage centered at − 1 V of frequency, f.

PSRR (dB) = 10 log(PµModule_IN/PµModule_OUT)

where:

PµModule_IN is the power at the frequency, f, at each of the VDD,

VS+, and VS− supply pins.

PµModule_OUT is the power at the frequency, f, in the µModule output.
