age reference input impedance will vary with
MCLK.
The voltage reference external RC filter series
resistor creates a voltage divider with the
VREF input impedance to reduce the effective
applied input voltage. To minimize gain error
resulting from this voltage divider effect, the
RC filter series resistor should be the minimum
size recommended in the voltage reference
device data sheet.
7.5 VREF Accuracy
The nominal voltage reference input is speci-
fied as 2.500 V across the VREF

pins, and all
fications are measured using a nominal volt-
age reference input. Any variation from a
nominal VREF input will proportionally vary the
analog full-scale gain accuracy.
Since temperature drift of the voltage refer-
ence results in gain drift of the analog full-scale
amplitude, care should be taken to minimize
temperature drift effects through careful selec-
tion of passive components and the voltage
reference device itself. Gain drift specifications
of the CS5371A and CS5372A do not include
the temperature drift effects of external pas-
sive components or of the voltage reference
device itself.
