MAX9004EUB-T

Overview

The MAX9004EUB-T is a low-power, high-speed single-supply integrated circuit combining an operational amplifier, a comparator, and a precision voltage reference. It operates from +2.5V to +5.5V supplies with quiescent current typically at 410µA. The op-amp offers an 8MHz gain-bandwidth product and unity-gain stability for gains of +10V/V or greater. The device includes a shutdown mode reducing current to 2µA and features rail-to-rail outputs.

Feature Summary

• Integrates high-speed op amp, fast comparator, and precision reference in space-saving package
• Features shutdown mode for ultra-low power consumption in portable applications
• Provides rail-to-rail input and output swing for maximum dynamic range
• Includes internal ±2mV comparator hysteresis for noise immunity

Applications

• Single-supply zero-drift photodiode preamplifiers
• Crossing detectors and smart card readers
• Infrared receivers and bar-code readers for remote controls
• Keyless entry systems and sensor signal detection

Procurement Notes

Verify the specific suffix EUB corresponds to the 10-pin µMAX package and industrial temperature range when sourcing. Confirm the presence of the +T reel packaging designation if tape-and-reel delivery is required for automated assembly processes.

Selection Notes

Select this component when system design requires a combined amplification, comparison, and reference function within a compact footprint. It is suitable for battery-powered devices requiring extended standby life through its dedicated shutdown capability and low active current draw.

Part Context

This part belongs to the MAX9000 family of mixed-signal ICs designed for single-supply operation. The family differentiates models based on op-amp bandwidth, reference inclusion, and shutdown functionality, providing designers with flexible options for various signal conditioning needs.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Ensure any replacement maintains compatibility with the 10-pin µMAX form factor and electrical specifications for single-supply operation.

FAQ

What is the gain stability requirement for the MAX9004 op-amp?

The MAX9004 op-amp is decompensated and is stable only for closed-loop gains of +10V/V or greater.

How does the shutdown mode affect the MAX9004 outputs?

Activating the shutdown mode reduces supply current to 2µA and places both the amplifier and comparator outputs into a high-impedance state.
