DESCRIPTION
The ADS8482 is an 18-bit, 1-MSPS A/C converter
with
an
internal
4.096-V
pseudo-bipolar, fully differential input. The device
includes a 18-bit capacitor-based SAR A/D converter
with inherent sample and hold. The ADS8482 offers
a full 18-bit interface, a 16-bit option where data is
read using two read cycles, or an 8-bit bus option
using three read cycles.
