MAX9002EUA

Overview

The MAX9002EUA is a low-power, high-speed single-supply operational amplifier integrated into the MAX9000 family. It operates from a +2.5V to +5.5V supply with a typical quiescent current of 340µA. The device features a unity-gain stable op amp with a 1.25MHz gain-bandwidth product and an 850mV/µs slew rate. It includes a fast comparator with 185ns propagation delay and ±2mV built-in hysteresis. The outputs are rail-to-rail, and the package is an 8-pin µMAX.

Feature Summary

• Combines a high-speed op amp, comparator, and precision reference in a space-saving µMAX package
• Unity-gain stable operation with a 1.25MHz gain-bandwidth product
• Rail-to-rail output swing for both the op amp and comparator
• Internal ±2mV comparator hysteresis provides noise immunity

Applications

• Single-supply zero-drift photodiode preamps
• Crossing detectors for signal processing
• Smart card readers and infrared receivers
• Bar-code readers for remote controls
• Keyless entry sensor signal detection

Procurement Notes

Verify the specific ordering suffix and temperature range when sourcing this component. Confirm that the manufacturer documentation aligns with the required pin configuration and electrical characteristics for your design. Ensure compliance with all absolute maximum ratings during implementation.

Selection Notes

Select the MAX9002EUA when a unity-gain stable amplifier is required alongside a comparator without an internal voltage reference. This part is suitable for applications needing ground-sensing inputs and low power consumption. Consider the MAX9000 or MAX9003 if an internal precision reference is necessary for the circuit design.

Part Context

The MAX9002EUA belongs to the MAX9000 series of mixed-signal ICs manufactured by Analog Devices / Maxim Integrated. These devices integrate multiple analog functions into a single compact package to reduce board space. The 'EUA' designation indicates an industrial temperature range and an 8-pin µMAX package format.

Replacement Considerations

Consult the official datasheet selector guide for direct replacements within the MAX9000 family. Verify that any substitute maintains the same gain stability, package dimensions, and electrical performance requirements.
