Ultra Low-Power, Low-Cost
Comparators with 2% Reference
_______________General Description
The MAX931-MAX934 single, dual, and quad micropower,
low-voltage comparators plus an on-board 2% accurate
reference feature the lowest power consumption available.
These comparators draw less than 4µA supply current
over temperature (MAX931), and include an internal
1.182V ±2% voltage reference, programmable hysteresis,
and TTL/CMOS outputs that sink and source current.
Ideal for 3V or 5V single-supply applications, the
MAX931-MAX934 operate from a single +2.5V to +11V
supply (or a ±1.25V to ±5V dual supply), and each
comparator’s input voltage range extends from the
negative supply rail to within 1.3V of the positive supply.
The MAX931-MAX934’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 MAX931-MAX934 minimize
parasitic feedback, which makes them easier to use.
The single MAX931 and dual MAX932/MAX933 provide a
unique and simple method for adding hysteresis without
feedback and complicated equations, using the HYST pin
and two resistors.
For applications that require increased precision with
similar power requirements, see the MAX921-MAX924 data
sheet. These devices include a 1% precision reference.
