Test Conditions/Comments
The ADC can convert signals presented to the
VH, VPx, and VXx pins; VPx and VH input signals
are attenuated depending on the selected
range; a signal at the pin corresponding to the
selected range is from 0.573 V to 1.375 V at the
ADC input
Endpoint corrected, V
V
One conversion on one channel
All eight channels selected, averaging enabled
V
Direct input (no attenuator)
Four DACs are individually selectable for
centering on one of four output voltage ranges
Same range, independent of center point
