MAX9013ESA

Overview

The MAX9013ESA is a single-channel, high-speed analog comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 4.5V to 5.5V power supply with a typical quiescent current of 1.3mA and maximum of 2.3mA. The device features a typical propagation delay of 5ns and an input offset voltage of ±0.7mV at +25°C. It provides TTL-compatible complementary outputs and includes a latch enable (LE) input. The common-mode input range extends from -0.2V to VCC-1.9V, allowing operation below ground. It is housed in an 8-pin SO package and functions over an extended temperature range of -40°C to +85°C.

Feature Summary

• Features ultra-fast 5ns propagation delay for high-speed signal processing applications.
• Includes a latch enable function that holds the output state when activated.
• Provides stable operation without oscillation in the linear region, eliminating minimum slew-rate requirements.
• Offers complementary TTL-compatible outputs for flexible logic interfacing.

Applications

• High-Speed Signal Squaring
• Zero-Crossing Detectors
• Fast Pulse-Width/Height Discriminators

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'ESA' corresponds to the 8-pin SO package variant. Check for RoHS compliance status as indicated on official documentation. Ensure design compatibility with the required 4.5V to 5.5V single-supply voltage range before procurement.

Selection Notes

Select this component for designs requiring precise differential comparison with low offset voltage. The inclusion of a latch function makes it suitable for sampling circuits where output state retention is necessary. Consider the complementary outputs if both true and inverted signals are required. Ensure the application benefits from the absence of hysteresis-induced resolution loss compared to standard comparators.

Part Context

This part belongs to the MAX901x family of precision TTL comparators, which also includes the MAX9010, MAX9011, and MAX9012. While sharing similar speed and power characteristics, the MAX9013 is distinguished by its single-channel configuration with complementary outputs and integrated latch capability. It serves as an improved replacement for legacy parts like the MAX913 in single-supply applications.

Replacement Considerations

The datasheet identifies the MAX9013 as an improved plug-in replacement for the industry-standard MAX913 and LT1016/LT1116. These alternatives offer lower power consumption and higher speed when utilized in single 5V supply applications. Verify pinout compatibility and electrical parameter alignment before substitution.

FAQ

Does the MAX9013 require hysteresis to prevent oscillation?

No, the device is designed to remain stable through the linear region without requiring built-in or external hysteresis, which helps maintain high resolution.

What is the function of the LE pin on the MAX9013?

The LE (Latch Enable) pin allows the user to hold the comparator's output state. When driven high, the output remains latched regardless of subsequent input changes.
