Product Details
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.
