MAX9032ASA

Overview

The MAX9032ASA+ is a dual-channel analog comparator optimized for single-supply applications operating from +2.5V to +5.5V. It features a propagation delay of 188ns and consumes 35µA of supply current per channel across the -40°C to +125°C temperature range. The device includes 4mV of built-in hysteresis for noise immunity and supports rail-to-rail output swings. Input common-mode voltage extends from the negative supply to within 1.1V of the positive supply, ensuring compatibility with low-voltage logic interfaces.

Feature Summary

• Dual-channel architecture providing two independent comparators in an 8-pin package
• Internal 4mV hysteresis prevents oscillations during slow-moving input transitions
• Rail-to-rail output stage reduces switching current glitches on the power supply
• No phase reversal occurs when inputs are overdriven beyond the supply rails

Applications

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

Procurement Notes

Verify the suffix 'V+' indicates automotive qualification and lead-free/RoHS compliance. Confirm the 'SO' package code matches the required 8-pin small outline footprint. Ensure the ordering part number aligns with the specified -40°C to +125°C temperature range. Cross-reference the manufacturer's official documentation for any recent pinout or electrical characteristic updates.

Selection Notes

Select this component when dual comparators are required in a compact surface-mount form factor. The 8-pin SO package offers a balance between pin count and board space. Verify that the 188ns propagation delay meets system timing requirements. Ensure the 35µA quiescent current fits the power budget constraints for the specific application environment.

Part Context

This device belongs to the MAX903x family of low-cost, ultra-small single/dual/quad comparators manufactured by Maxim Integrated (now Analog Devices). The MAX9032 specifically provides dual channels, distinguishing it from the single-channel MAX9031 and quad-channel MAX9034 variants. All members share similar electrical characteristics and packaging options.

Replacement Considerations

Direct substitutes include other parts from the MAX903x family such as the MAX9032AUA+ (µMAX package) or MAX9032AKA+ (SOT23 package). These alternatives maintain identical electrical performance but differ in physical package dimensions and pin configurations.
