DESCRIPTION

The ADS7955-Q1 is a 10-bit multichannel

analog-to-digital converter.

The device includes a capacitor based SAR A/D

converter with inherent sample and hold.

The device accepts a wide analog supply range from

2.7V to 5.25V. Very low power consumption makes

this device 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. The device allows auto

sequencing of preselected channels or manual selection of a channel for the next conversion cycle.

There are two software selectable input ranges (0V -

2.5V and 0V - 5V), four individually configurable

GPIOs, and two programmable alarm thresholds per

channel. These features make the device suitable for

most data acquisition applications.

The device offers an attractive power-down feature.

This is extremely useful for power saving when the

device is operated at lower conversion speeds.
