Single-Supply Comparators

MAX9024

General Description

Features

● Low-Cost Solution Available in Space-Saving

SC70 Packages (Half the Size of SOT23)

● Low 2.8μA Supply Current

The MAX9021/MAX9022/MAX9024 single/dual/quad com-

parators 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 consume 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.

● 3μs Propagation Delay

● Internal 4mV Comparator Hysteresis

● Comparator Output Swings Rail-to-Rail

● 2.5V to 5.5V Single-Supply Voltage Range

● No Phase Reversal for Overdriven Inputs

● Space-Saving Packages

• 5-Pin SC70 (MAX9021)

• 8-Pin SOT23 (MAX9022)

• 8-Pin μMAX (MAX9022)

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 com-

parator-output stage substantially reduces switching current

during output transitions, eliminating power-supply glitches.
