MAX9005ESA-T

Overview

The MAX9005ESA-T is a low-power, high-speed single-supply integrated circuit combining an operational amplifier, a comparator, and precision voltage reference components within a compact 8-pin SOIC package. It operates from a +2.5V to +5.5V supply with typical quiescent current of 340µA. The op-amp features an 8MHz gain-bandwidth product and stable closed-loop gains of +10V/V or greater. The comparator provides fast 185ns propagation delay with built-in hysteresis for noise immunity.

Feature Summary

• Combines high-speed op amp, fast comparator, and precision reference in space-saving 8-pin SOIC package
• Operates from +2.5V to +5.5V single supply with ultra-low power consumption
• Rail-to-Rail outputs deliver up to ±2.5mA (op amp) and ±4.0mA (comparator)
• Built-in ±2mV comparator hysteresis prevents oscillations with slow-moving signals

Applications

• Single-Supply Zero-Photodiode Preamps
• Smart Card Readers
• Infrared Receivers and Bar-Code Readers for Remote Controls
• Keyless Entry Sensor Signal Detection

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm the device availability status as discontinued through official Analog Devices channels. Ensure compatibility with existing PCB footprints for the 8-SOIC package format.

Selection Notes

Select this component when requiring a combined signal chain solution in minimal board space. Choose over discrete alternatives if system constraints demand reduced component count and lower total power dissipation. Verify that the decompensated op-amp stability requirements match the intended closed-loop gain applications.

Part Context

This part belongs to the MAX9000 family of mixed-signal ICs designed for portable electronics. It shares architectural similarities with the MAX9000, MAX9001, MAX9002, MAX9003, and MAX9004 variants. The primary distinction lies in the absence of an internal voltage reference and shutdown functionality compared to other family members.

Replacement Considerations

No official substitute part numbers are confirmed in the provided documentation.

FAQ

Does the MAX9005 include an internal voltage reference?

No, the MAX9005 does not feature an internal precision reference; only the MAX9000, MAX9001, MAX9003, and MAX9004 variants include this component.

What is the gain stability requirement for the op-amp in this device?

The op-amp is decompensated and is stable for closed-loop gains of +10V/V or greater, utilizing an 8MHz gain-bandwidth product.
