ADS7953 Multichannel ADC Converters

ADS7953 Multichannel ADC Converters

Texas Instruments' ADS7953 is a 12/10/8-bit multichannel analog-to-digital converter with a capacitor-based SAR A/D converter with inherent sample and hold. It accepts a wide analog supply range from 2.7 V to 5.25 V. Very low power consumption makes these devices suitable for battery-powered and isolated power supply applications. A wide 1.7 V to 5.25 V I/O supply range facilitates a glue-less interface with the most commonly used CMOS digital hosts.
