DESCRIPTION
The ADS8323 is a 16-bit, 500kSPS Analog-to-Digital Con-
verter (ADC) with an internal 2.5V reference. The device
includes a 16-bit capacitor-based SAR ADC with inherent
sample-and-hold. The ADS8323 offers a full 16-bit interface,
or an 8-bit option where data is read using two read cycles.
The ADS8323 is available in a TQFP-32 package and is
specified over the industrial –40°C to +85°C temperature
range.
