MAX9011EUT+T

Overview

The MAX9011EUT+T is a single-channel, high-speed analog comparator from the MAX9010–MAX9013 family. It operates on a single 4.5V to 5.5V supply with a typical quiescent current of 900µA and propagation delay of 5ns. The device features precision differential inputs with an input offset voltage of ±0.7mV at +25°C and extends its common-mode range down to -0.2V. It includes a TTL-compatible latch enable (LE) pin for output state holding and outputs in a 6-pin SOT-23 package.

Feature Summary

• Ultra-fast 5ns propagation delay with low quiescent current consumption
• Precision differential inputs with extended common-mode range including ground
• Integrated TTL-compatible latch function via dedicated LE pin
• Stable operation in linear region without minimum slew-rate requirement

Applications

• High-speed signal squaring circuits
• Zero-crossing detectors
• Fast pulse-width/height discriminators
• High-speed sampling circuits

Procurement Notes

Verify the component matches the exact part number MAX9011EUT+T, ensuring the suffix indicates the standard tape-and-reel packaging format. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated and check that the device meets RoHS compliance standards before finalizing procurement specifications.

Selection Notes

Select this comparator when a single-channel solution with integrated latching is required. It is suitable for designs needing precise threshold detection with minimal power draw. Ensure the application utilizes a single 5V supply and requires TTL-compatible logic levels for interfacing with downstream digital components.

Part Context

This component belongs to the MAX9010–MAX9013 series of precision TTL comparators. While the MAX9010 lacks a latch, the MAX9011 adds the latch enable feature. The MAX9012 provides dual channels, and the MAX9013 offers complementary outputs. All variants share similar electrical characteristics and are designed for high-speed, low-power applications.

Replacement Considerations

The MAX9013 serves as an improved plug-in replacement for industry-standard parts like the MAX913 and LT1016/LT1116 in single-supply applications. Verify pinout compatibility and ensure the replacement supports the required latch functionality if present in the original design.

FAQ

How does the MAX9011 handle slow-moving input signals?

The MAX9011 remains stable through the linear region when driven by slow-moving or low input-overdrive signals, eliminating the output instability common to other high-speed comparators.

What is the function of the LE pin on the MAX9011?

The Latch Enable (LE) pin allows the user to hold the comparator's output state. When driven high, it latches the existing output; when low or grounded, the output follows the input differential voltage.

Can the MAX9011 inputs go below ground?

Yes, the input voltage range extends to 200mV below ground without causing output phase reversal, provided at least one input remains within the specified common-mode range.
