Overview
Description
The ADS7891 is a 14-bit, 3-MSPS analog-to-digital converter with an internal 2.5-V reference. It features a capacitor-based SAR architecture with inherent sample and hold. The device offers a 14-bit parallel interface with an additional byte mode for easy interfacing with 8-bit processors. It has a pseudo-differential input stage with a ±200 mV -IN swing to compensate for ground voltage mismatch and cancel common-mode noise. The ADS7891 includes an internal reference buffer and supports 8-/14-bit bus transfer. It is available in a 48-pin TQFP package.

Features
3 MHz sample rate, 14-bit resolution
Zero latency
Unipolar, pseudo-differential input, range: -0 V to 2.5 V
High-speed parallel interface
78 dB SNR and 88.5 dB THD at 3 MSPS
