DESCRIPTION
The ADS8422 is a 16-bit, 4-MHz A/D converter with
an internal 4.096-V reference. The device includes a
16-bit capacitor-based multi-bit SAR A/D converter
with inherent sample and hold. This converter
includes a full 16-bit interface and an 8-bit option
where data is read using two 8-bit read cycles if
necessary.
