MAX9024AUD+

Overview

The MAX9024AUD+ is a quad micropower comparator from the Analog Devices/MAXIM Integrated MAX902x family, housed in a 14-pin TSSOP package. 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 only 2.8µA of supply current per comparator across an operating temperature range of -40°C to +125°C. It includes built-in 4mV hysteresis for noise immunity and provides rail-to-rail output swing with no phase reversal for overdriven inputs.

Feature Summary

• Ultra-low power consumption optimized for portable applications
• Built-in internal hysteresis prevents oscillations with slow-moving signals
• Rail-to-rail output stage eliminates power-supply glitches during transitions
• No phase reversal occurs even when inputs are overdriven

Applications

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

Procurement Notes

Verify the specific suffix 'AUD+' indicates a lead-free/RoHS-compliant version in the 14-pin TSSOP package. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the component matches the quad comparator configuration within the specified electrical parameters before integration into designs.

Selection Notes

Select this component when multiple comparators are required in space-constrained designs. The quad configuration reduces board area compared to using individual single or dual units. Verify that the 3µs propagation delay meets system timing requirements and that the 2.5V minimum supply voltage aligns with the available power rails.

Part Context

This part belongs to the MAX9021/MAX9022/MAX9024 series of micropower, ultra-small, single/dual/quad comparators. The MAX9024 specifically provides four independent comparators in one package, sharing the same low-power architecture and input characteristics as its single (MAX9021) and dual (MAX9022) counterparts.

Replacement Considerations

The obsolete MAX9024AUD can be replaced directly by the MAX9024AUD+ variant.
