MAX921 Low-Power Voltage Comparators Datasheet

The MAX921 is a single micro-power, low voltage comparator. The comparator draws less than 4µA and includes an internal 1.182V voltage reference. The MAX921 also includes programmable hysteresis and TTL/CMOS compatible outputs. The MAX921 can operate from a single or dual power supplies and the input voltage range can swing from the negative supply rail to within 1.3V of the positive supply.
