ADS7886 - SAR Analog-to-Digital Converter

General Description

The ADS7886 is a 12-bit, 1-MSPS analog-to-digital converter (ADC).

The device includes a capacitor based SAR A/D converter with inherent sample and hold.

The serial interface in each device is controlled by the CS and SCLK signals for glueless connections with microprocessors and DSPs.
