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 8-pin SOT23 package and operates within a temperature range of -40°C to +125°C. The device consumes 35µA per comparator with a propagation delay of 188ns. It includes internal 4mV hysteresis and rail-to-rail output swing.
Feature Summary
- Dual-channel configuration in an ultra-small 8-pin SOT23 package
- Internal 4mV hysteresis for noise immunity
- Rail-to-rail output capability
- 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 'AKA' corresponds to the 8-pin SOT23 package variant. Confirm RoHS compliance indicated by the '+' symbol. Ensure the tape-and-reel designation '+T' matches manufacturing requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and revision status before procurement.
Selection Notes
Select this component when a dual-channel comparator is required in space-constrained designs. It is suitable for low-voltage single-supply operation down to 2.5V. Consider the 188ns propagation delay and 35µA current consumption for power-sensitive portable applications. Verify that the 4mV internal hysteresis meets noise rejection requirements without external feedback components.
Part Context
This part belongs to the MAX903x series of low-cost, ultra-small comparators manufactured by Analog Devices/Maxim Integrated. The series includes single (MAX9030/MAX9031), dual (MAX9032), and quad (MAX9034) variants. The MAX9032 specifically provides two independent comparators in compact packages like SOT23 and µMAX, targeting portable electronics.
Replacement Considerations
Direct substitutes include other MAX9032 variants such as MAX9032AUA+ or MAX9032ASA+, which offer different package options like µMAX or SO while maintaining identical electrical characteristics.
