DESCRIPTION
The ADS8381 is an 18-bit, 580 kHz A/D converter. The
device includes a 18-bit capacitor-based SAR A/D
converter with inherent sample and hold. The ADS8381
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 ADS8381 is available in a 48-lead TQFP package and
is characterized over the industrial −40°C to 85°C
temperature range.
