PSR is a measure of the data converter’s level of immu-
nity to power-supply fluctuations. PSR assumes that the
converter’s linearity is unaffected by changes in the
power-supply voltage. Power-supply rejection ratio
(PSRR) is the ratio of the input signal change to the
change in the converter output. PSRR is typically mea-
sured in dB.

Note: The V/I converter current output (4–20mA)
power-supply rejection is with respect to the 7V to 30V
loop supply.
