Product Descriptions
The MAX931-MAX934 single, dual, and quad micropower, low-voltage comparators plus an on-board 2 PERCENT 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 PERCENT 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 powersupply 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 PERCENT precision reference.
