DESCRIPTION
The ADS8402 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 ADS8402 offers a full 16-bit interface and an
8-bit option where data is read using two 8-bit read cycles.
The ADS8402 has a unipolar differential input. It is
available in a 48-lead TQFP package and is characterized
over the industrial –40°C to 85°C temperature range.
