The ADS8422 is a 16-bit, 4-MHz A/D converter with an internal 4.096-V reference. The device includes a 16-bit capacitor-based multi-bit SAR A/D converter with inherent sample and hold. This converter includes a full 16-bit interface and an 8-bit option where data is read using two 8-bit read cycles if necessary.
●The ADS8422 has a fully differential, pseudo-bipolar input. It is available in a 48-lead TQFP package and is characterized over the industrial -40°C to +85°C temperature range.
