MAX934ESE+T

Comparators Overview

The MAX934ESE+T is a quad micropower, low-voltage analog comparator manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 ±2% bandgap reference and TTL/CMOS-compatible outputs capable of sourcing up to 40mA continuously. It exhibits a typical propagation delay of 12µs with 10mV overdrive and draws less than 6.5µA supply current. The input voltage range extends from the negative rail to within 1.3V of the positive rail. It is housed in a 16-pin SO-Narrow package.

Comparators Feature Summary

• Integrates an internal 1.182V bandgap voltage reference with ±2% accuracy
• Features unique output stage that eliminates switching crowbar currents during transitions
• Provides continuous source current capability of up to 40mA per comparator
• Supports adjustable hysteresis implementation via dedicated HYST pin

Comparators Applications

• Battery-powered systems requiring ultra-low quiescent current
• Threshold detectors for voltage monitoring
• Window comparators for undervoltage/overvoltage detection
• Oscillator circuits utilizing internal reference
• Alarm circuits with noise margin enhancement

Comparators Procurement Notes

Verify the specific suffix '+T' indicates reel packaging when ordering. Confirm the 'E' suffix corresponds to the -40°C to +85°C extended temperature range. Ensure the 16-pin SO-Narrow footprint matches the target PCB design. Cross-reference the manufacturer part number MAX934ESE+T with official Analog Devices documentation to confirm current production status and RoHS compliance details before finalizing procurement.

Comparators Selection Notes

Select this component when four independent comparators are required alongside a precise internal reference. It is suitable for designs needing high output drive capability without external buffering. Consider the 12µs propagation delay for timing-sensitive applications. Verify that the input common-mode range meets the signal requirements relative to the supply rails. Compare against the MAX924 if higher precision (1%) reference is needed, noting pin compatibility differences.

Comparators Part Context

This device belongs to the MAX931-MAX934 family of micropower comparators. The MAX934 specifically integrates four comparators in a 16-pin package. It shares architectural similarities with the MAX921-MAX924 series but offers lower cost and slightly different reference accuracy. The family is designed for single-supply operation with minimal power consumption, making it distinct from high-speed comparator families.

Comparators Replacement Considerations

The MAX924ESE+T is a pin-compatible alternative offering 1% reference accuracy instead of 2%. Verify functional equivalence regarding output swing and propagation delay characteristics before substitution.
