The ADS79xx-Q1 device family consists of multichannel 8-bit, 10-bit and 12-bit analog-to-digital converters (ADCs). The devices include a capacitor-based successive approximation register (SAR) ADC with inherent sample and hold. Multiple features and great performance makes the ADS79xx-Q1 device useful for wide variety of applications where multiple channels should be monitored.
The ADS79xx-Q1 device works on a wide analog-supply range from 2.7 V to 5.25 V. These devices are suitable for battery-powered and isolated power-supply applications because of very-low power consumption.
The 4- and 8-channel devices are available in 30-pin TSSOP package. The 12- and 16-channel devices are available in 38-pin TSSOP package.
