MAX9032AUA

Overview

The MAX9032AUA+ is a dual analog comparator from the MAX9030/MAX9031/MAX9032/MAX9034 family, optimized for single-supply applications operating between +2.5V and +5.5V. It features a propagation delay of 188ns and consumes 35µA of supply current per comparator across the -40°C to +125°C temperature range. The device includes 4mV of built-in hysteresis for noise immunity and offers rail-to-rail output swing with no phase reversal for overdriven inputs.

Feature Summary

• Rail-to-rail output voltage swing capability
• Internal 4mV comparator hysteresis for noise immunity
• No phase reversal for overdriven inputs

Applications

• Battery-powered systems
• Portable equipment
• Mobile communications devices
• Sensor signal detection circuits
• Photodiode preamplifiers

Procurement Notes

Verify the specific suffix 'AUA+' corresponds to the µMAX-8 package variant when sourcing. Confirm RoHS compliance status as indicated by the '+' designation in ordering information. Ensure the procurement channel supports the required surface-mount installation style and valid temperature range specifications for the target application environment.

Selection Notes

Select this component for designs requiring low power consumption and small footprint in portable electronics. The dual-channel configuration suits applications needing two independent comparison functions without shutdown control. Consider the 188ns propagation delay and 4mV internal hysteresis for signal integrity requirements in noisy environments or slow-moving input scenarios.

Part Context

This part belongs to the MAX903x series of low-cost, ultra-small comparators manufactured by Analog Devices Inc./Maxim Integrated. The series includes single (MAX9030/MAX9031), dual (MAX9032), and quad (MAX9034) variants. The MAX9032 specifically provides two comparators in compact packages like SOT23 and µMAX, distinguishing it from the shutdown-enabled MAX9030.

Replacement Considerations

Compatible substitutes within the same family include MAX9032AKA+T (SOT23-8) and MAX9032ASA+ (SOIC-8). Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit on the PCB layout.
