Part Number : MAX998ESA
Function : Quad, single-supply, high-speed, low-power comparator.
Maker : Maxim Integrated
The MAX976/MAX978/MAX998 dual/quad/single, high speed, low-power comparators are optimized for +3V/+5V single-supply applications. They achieve a 20ns propagation delay while consuming only 225µA supply current per comparator. The MAX998 features a low-power shutdown mode that places the output in a high-impedance state and reduces supply current to 1nA.
The MAX976/MAX978/MAX998 inputs have a common mode voltage range that extends 200mV below ground.
Their outputs are capable of rail-to-rail operation with out external pullup circuitry, making these devices ideal for interface with CMOS/TTL logic. All inputs and out puts can tolerate a continuous short-circuit fault condi
tion to either rail. The comparators’ internal hysteresis ensures clean output switching, even with slow-moving input signals.
For space-critical applications, the single MAX998 is available in a 6-pin SOT23 package, the dual MAX976 is available in an 8-pin µMAX®package, and the quad MAX978 is available in a 16-pin QSOP package.
