analog ground pin. No analog ground pin is re-
quired because the inputs for measurement and
for the voltage reference are differential and re-
quire no ground. In the digital section of the
chip the supply current flows into the VD+ pin
and out of the DGND pin. As a CMOS device,
the CS5505/6/7/8 requires that the supply volt-
age on the VA+ pin always be more positive
than the voltage on any other pin of the device.
If this requirement is not met, the device can
latch-up or be damaged. In all circumstances the
VA+ voltage must remain more positive than the
