MAX9032AKA-T

Overview

The MAX9032AKA-T is a dual analog comparator from the MAX9030/MAX9031/MAX9032/MAX9034 family, optimized for single-supply applications ranging from +2.5V to +5.5V. It features an ultra-small 8-pin SOT23 package and consumes 35µA of supply current per comparator over the -40°C to +125°C operating temperature range. The device exhibits a propagation delay of 188ns and includes 4mV of built-in hysteresis to ensure noise immunity. Input common-mode voltage extends from the negative supply to within 1.1V of the positive supply.

Feature Summary

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

Applications

• Battery-powered systems
• Portable equipment
• Mobile communications devices
• Sensor signal detection circuits
• Threshold detectors and discriminators

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'A' designation aligns with the required -40°C to +125°C industrial temperature range. Ensure the ordering code matches the exact pinout and package dimensions specified in the official datasheet documentation before finalizing procurement.

Selection Notes

Select this component when a dual-channel comparator is required in space-constrained designs. It is suitable for low-power portable applications due to its 35µA quiescent current. Verify that the input signal characteristics fall within the specified common-mode range and that the 188ns propagation delay meets system timing requirements.

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), dual (MAX9032), and quad (MAX9034) variants. The MAX9032 specifically provides two independent comparators in an 8-pin footprint, distinguishing it from the single-channel MAX9031 and quad-channel MAX9034.

Replacement Considerations

Direct functional substitutes within the same family include MAX9032ASA+ and MAX9032AUA+. These parts share identical electrical specifications but differ in package type (SO or µMAX vs. SOT23). Cross-package replacements require PCB layout modifications.
