DESCRIPTION
The ADS8371 is an 16-bit, 750 kHz A/D converter. The
device includes a 16-bit capacitor-based SAR A/D
converter with inherent sample and hold. The ADS8371
offers a full 16-bit interface or an 8-bit bus option using two
read cycles.
The ADS8371 is available in a 48-lead TQFP package and
is characterized over the industrial −40°C to 85°C
temperature range.
