The device comparison table shows all twelve devices from this product family.
The devices include a capacitor based SAR A/D converter with inherent sample and hold.
The devices accept 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.
