MAX922ESA-T

Comparators Overview

The MAX922ESA-T is a dual micro-power, low-voltage comparator in an 8-pin SO package. It operates from a single +2.5V to +11V supply or ±1.25V to ±5.5V dual supply. The device draws less than 4μA supply current over temperature and features TTL/CMOS outputs that sink and source current. Each comparator input voltage range swings from the negative supply rail to within 1.3V of the positive supply. The unique output stage continuously sources up to 40mA and eliminates power-supply glitches during logic state changes.

Comparators Feature Summary

• Ultra-low quiescent current consumption suitable for battery-powered systems
• TTL/CMOS-compatible outputs capable of sourcing up to 40mA continuously
• Wide common-mode input voltage range extending to the negative supply rail
• Output stage design minimizes parasitic feedback by eliminating crowbar switching currents

Comparators Applications

• Battery-powered systems
• Threshold detectors
• Window comparators
• Oscillator circuits

Comparators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'E' designation corresponds to the -40°C to +85°C extended temperature range. Ensure the manufacturer is identified as Analog Devices Inc./Maxim Integrated. Check for RoHS compliance status if required by project specifications.

Comparators Selection Notes

Select this component for applications requiring low power consumption with dual comparator functionality. It is suitable for single or dual supply designs where input signals approach the negative rail. The high output drive capability allows direct interfacing with digital logic without additional buffering. Consider the propagation delay characteristics relative to signal speed requirements.

Comparators Part Context

This part belongs to the MAX921–MAX924 family of ultra low-power comparators. While the MAX921 and MAX923 include internal hysteresis and reference options, the MAX922 provides two independent comparators without these integrated features. It shares the same low-power architecture and output drive capabilities as its siblings but focuses on basic comparison functions.
