The devices include a capacitorbased 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 analogsupply range from 2.7 V to 5.25 V. These devices are suitable for battery-powered and isolated powersupply 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.
