Micropower, Ultra-Small, Single/Dual/Quad,

Single-Supply Comparators

General Description

Features

The MAX9021/MAX9022/MAX9024 single/dual/quad

comparators are optimized for low-power consumption

while still providing a fast output response. They are

designed for single-supply applications from 2.5V to

5.5V, but can also operate from dual supplies. These

comparators have a 3µs propagation delay and con-

sume 2.8µA of supply current per comparator over the

-40°C to +125°C operating temperature range. The

combination of low-power, single-supply operation

down to 2.5V, and ultra-small footprint makes these

devices ideal for portable applications.

ꢀ Low-Cost Solution Available in Space-Saving

SC70 Packages (Half the Size of SOT23)

ꢀ Low 2.8µA Supply Current

ꢀ 3µs Propagation Delay

ꢀ Internal 4mV Comparator Hysteresis

ꢀ Comparator Output Swings Rail-to-Rail^®

ꢀ 2.5 to 5.5V Single-Supply Voltage Range

ꢀ No Phase Reversal for Overdriven Inputs

The MAX9021/MAX9022/MAX9024 have 4mV of built-in

hysteresis to provide noise immunity and prevent oscil-

lations even with a slow-moving input signal. The input

common-mode range extends from the negative supply

to within 1.1V of the positive supply. The design of the

comparator-output stage substantially reduces switch-

ing current during output transitions, eliminating power-

supply glitches.

5-Pin SC70 (MAX9021)

8-Pin SOT23 (MAX9022)

Ordering Information

The MAX9021 single comparator is available in tiny 5-

pin SC70 and SOT23 packages. The MAX9022 dual

comparator is available in 8-pin SOT23, µMAX, and SO

packages, and the MAX9024 quad comparator is avail-

able in 14-pin TSSOP and SO packages.
