Description

The ADS79XX is a 12/10/8-bit multichannel analog-to-digital converter family. The following table shows all twelve devices from this product family.

The devices include a capacitor based SAR A/D converter with inherent sample and hold.

The devices accept a wide analog supply range from 2.7V to 5.25V. Very low power consumption makes these devices suitable for battery-powered and isolated power supply applications.

A wide 1.7V to 5.25V I/O supply range facilitates a glue-less interface with the most commonly used CMOS digital hosts.

The serial interface is controlled by CS and SCLK for easy connection with microprocessors and DSP.

The input signal is sampled with the falling edge of CS. It uses SCLK for conversion, serial data output, and reading serial data in.
