DESCRIPTION

The ADS8383 is an 18-bit, 500 kHz A/D converter. The

device includes a 18-bit capacitor-based SAR A/D

converter with inherent sample and hold. The ADS8383

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.

The ADS8383 is available in a 48-lead TQFP package and

is characterized over the industrial −40°C to 85°C

temperature range.
