This datasheet details the Texas Instruments ADS7955-Q1, a 10-bit, 1MSPS, 8-channel single-ended analog-to-digital converter with serial interface.
The ADS7955-Q1 is a 10-bit multichannel analog-to-digital converter designed for automotive applications and battery-powered systems. It features a 1-MHz sample rate, a wide analog supply range from 2.7V to 5.25V, and very low power consumption with a typical dissipation of 14.5mW at full speed.
The device includes an internal capacitor-based SARA/D converter and supports two software-selectable input ranges (0V-2.5V and 0V-5V). It offers auto and manual modes for channel selection, four individually configurable GPIOs, and two programmable alarm levels per channel to facilitate data acquisition applications.
