MAX924EPE

Comparators Overview

The MAX924EPE is a quad micro-power, low-voltage comparator housed in a 16-pin Plastic DIP package. It operates from a single +2.5V to +11V supply or dual ±1.25V to ±5.5V supplies. The device features an internal 1.182V ±1% bandgap reference and TTL/CMOS-compatible outputs capable of sourcing up to 40mA continuously. Quiescent current is typically 6.5µA at +25°C, rising to 8.5µA across the extended temperature range (-40°C to +85°C). Propagation delay is 12µs with 10mV overdrive.

Comparators Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Integrated precision voltage reference for simplified threshold setting
• High-current output stage eliminates crowbar switching glitches
• TTL/CMOS compatible logic levels for direct interfacing

Comparators Applications

• Battery-powered threshold detectors
• Window comparators for voltage monitoring
• Oscillator circuits
• Auto-off power switches

Comparators Procurement Notes

Verify the specific suffix EPE confirms the -40°C to +85°C operating range and 16-pin Plastic DIP package configuration. Confirm RoHS compliance status as indicated on the manufacturer's ordering information page. Ensure the component matches the exact Analog Devices / Maxim Integrated part number to avoid functional discrepancies with other variants in the MAX92x family.

Comparators Selection Notes

Select this component when multiple independent comparison channels are required within a single integrated circuit. The built-in reference simplifies design by removing external resistor networks for basic threshold applications. Consider the propagation delay characteristics against system timing requirements, as the device prioritizes low power over high-speed response compared to standard comparators.

Comparators Part Context

This device belongs to the MAX921–MAX924 family of micropower comparators. While the MAX921, MAX922, and MAX923 utilize 8-pin packages, the MAX924 specifically integrates four comparator channels into a 16-pin footprint. This family is distinguished by its ability to operate at very low supply voltages while maintaining stable performance across commercial and extended industrial temperature ranges.

Comparators Replacement Considerations

Direct pin-for-pin replacements within the same package include the MAX924CPE (commercial temperature range) and MAX924MJE (military temperature range). Verify that the thermal operating range of the substitute meets the application's environmental specifications.
