MAX921–MAX924
Ultra Low-Power, Single/Dual-Supply Comparators
General Description
The MAX921–MAX924 single, dual, and quad micro-power, low-
voltage comparators feature the lowest power consumption available.
These comparators draw less than 4μA supply current over temperature (MAX921/ MAX922), and include an internal 1.
182V ±1%
voltage reference, programmable hysteresis, and TTL/
CMOS outputs that sink and source current.
Ideal for 3V or 5V single-supply applications, the MAX921– MAX924 operate from a single +2.
5V to +11V supply (or a ±1.
25V to ±5V dual supply), and each comparator’s input
voltage range swings from the negative supp...
