AD7394/AD7395
output drive current, but consumes only 50 microamps inter-
nally. If higher resolution is required, the AD7394 can be used
with the addition of two more bits of data inserted into the
software coding, which would result in a 2.5 mV LSB step size.
Table VI shows examples of nominal output voltages, V
vided by the Bipolar Operation circuit application.
