DESCRIPTION
The ADS8412 is a 16-bit, 2 MHz A/D converter with
an internal 4.096-V reference. The device includes a
16-bit capacitor-based SAR A/D converter with in-
herent sample and hold. The ADS8412 offers a full
16-bit interface and an 8-bit option where data is read
using two 8-bit read cycles.
The ADS8412 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 tem-
perature range.
