MAX9024ASD-T

Overview

The MAX9024ASD-T is a quad, low-power voltage comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply of 2.5V to 5.5V or dual supplies of ±1.25V to ±2.75V. The device consumes 2.8µA per comparator and features a typical propagation delay of 3µs. It includes internal 4mV hysteresis for noise immunity and supports rail-to-rail output swing. The component is housed in a 14-pin SO package and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Low power consumption with 2.8µA supply current per comparator
• Internal 4mV hysteresis prevents oscillations on slow-moving signals
• Rail-to-rail output swing capability
• No phase reversal for overdriven inputs

Applications

• Battery-powered portable systems
• Sensor-signal detection
• Digital line receivers
• Threshold detectors/discriminators

Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging configuration. Confirm RoHS compliance status associated with the '+' designation if required for environmental regulations. Ensure the 14-pin SO package footprint matches the target PCB design constraints. Validate that the -40°C to +125°C temperature range aligns with the operational environment requirements.

Selection Notes

Select this component when space-saving quad comparator functionality is required alongside ultra-low power consumption. The built-in hysteresis eliminates the need for external feedback resistors in many noise-sensitive applications. Verify that the 3µs propagation delay meets the timing requirements of the specific signal processing application.

Part Context

This part belongs to the MAX9021/MAX9022/MAX9024 family of micropower comparators optimized for portable applications. The MAX9024 variant specifically provides four independent comparators in a single package, offering a cost-effective solution for multi-channel threshold detection without increasing board space significantly compared to single-channel alternatives.

Replacement Considerations

Direct substitutes include other members of the MAX902x family such as the MAX9021 (single) or MAX9022 (dual), provided the channel count requirement can be adjusted. Cross-referencing pin-compatible quad comparators with similar 2.8µA current draw and 4mV internal hysteresis specifications is recommended for direct replacement scenarios.
