The ADS8401 is a 16-bit, 1.25 MHz A/D converter with an internal 4.096-V reference. The device includes a 16-bit capacitor-based SAR A/D converter with inherent sample and hold. The ADS8401 offers a full 16-bit interface and an 8-bit option where data is read using two 8-bit read cycles.
The ADS8401 has a unipolar single-ended input. It is available in a 48-lead TQFP package and is characterized over the industrial 40°C to 85°C temperature range.
