MAX9024ASD+

Overview

The MAX9024ASD+ is a quad micropower comparator from the MAX9021/MAX9022/MAX9024 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.5V to 5.5V or dual supplies of ±1.25V to ±2.75V. The device features a typical propagation delay of 3μs and consumes 2.8μA of supply current per comparator across the -40°C to +125°C temperature range. It includes 4mV of internal hysteresis for noise immunity and offers rail-to-rail output swing with no phase reversal for overdriven inputs.

Feature Summary

• Micropower consumption optimized for portable applications
• Internal 4mV hysteresis prevents oscillations with slow-moving signals
• Rail-to-rail output swings eliminate power-supply glitches during transitions
• No phase reversal occurs even when inputs are overdriven

Applications

• Battery-powered portable systems
• Mobile communications equipment
• Sensor-signal detection circuits
• Photodiode preamplifiers
• Digital line receivers

Procurement Notes

Verify the specific package suffix 'SD' corresponds to the 14-pin SOIC footprint required for your design. Confirm RoHS compliance status indicated by the '+' suffix in ordering information. Ensure the operating environment stays within the specified -40°C to +125°C temperature range for guaranteed performance parameters.

Selection Notes

Select this component when low quiescent current is critical alongside moderate speed requirements. The quad configuration reduces board space compared to individual units. Verify that the 3μs propagation delay meets system timing constraints. Consider the 4mV internal hysteresis for basic noise filtering without external components.

Part Context

This part belongs to the MAX902x series of micropower comparators designed for single-supply operation. It complements the MAX9021 (single) and MAX9022 (dual) variants within the same family. The series emphasizes ultra-small footprints and low cost for battery-operated devices.

Replacement Considerations

Direct substitutes include other quad comparators from the MAX902x family such as the MAX9024AUD+ in TSSOP-14 packaging. Cross-reference pinouts and electrical characteristics carefully before substitution.
