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.
ldeal 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 suply), and each comparator's
input voltage range swings from the negative supply rail
to within 1.3V of the positive supply.
The MAX921-MAX924's unique output stage continuously
sources as much as 40mA. And by eliminating power-
supply glitches that commonly occur when comparators
change logic states, the MAX921- -MAX924 minimize
parasitic feedback, which makes them easier to use.
The single MAX921 and dual MAX923 provide a unique
and simple method for adding hysteresis without feed-
back and complicated equations, simply by using the
HYST pin and two resistors.
