These devices operate from a single +1.6V parator with a common hysteresis adjustment and a to +5.5V supply voltage range, and consume less than reference output pin. The MAX970 is a quad comparator 5µA supply current per comparator over the extended without a reference and without hysteresis adjustment. temperature range.
