MAX913EUA+

Overview

The MAX913EUA+ is a single, ultra-fast, low-power precision TTL comparator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features differential inputs and complementary TTL outputs, designed for high-speed applications with minimal power consumption. The device operates from a single +5V or dual ±5V supply, offering a wide common-mode input range that extends below the negative rail. Key electrical characteristics include a typical propagation delay of 10ns, an input offset voltage of 0.8mV, and a supply current of 6mA per comparator at +5V. It is housed in an 8-pin µMAX package and supports an extended temperature range of -40°C to +85°C.

Feature Summary

• Ultra-fast propagation delay of 10ns for high-speed signal processing
• Low power consumption with 6mA supply current per comparator
• Stable operation in the linear region without minimum slew-rate requirement
• Wide common-mode input range extending below the negative supply rail

Applications

• Zero-Crossing Detectors
• Ethernet Line Receivers
• Switching Regulators
• High-Speed Sampling Circuits
• Fast Pulse Width/Height Discriminators

Procurement Notes

Verify the specific ordering suffix 'EUA+' corresponds to the -40°C to +85°C temperature range and 8-pin µMAX package configuration. Confirm compatibility with existing board layouts requiring small surface-mount footprints. Ensure power supply bypassing meets the recommended 0.1µF ceramic capacitor specification near supply pins for optimal performance.

Selection Notes

Select this component when high speed and low power are critical constraints. It serves as an improved plug-in replacement for the LT1016, offering wider input voltage range and equivalent speed at lower power. Consider the µMAX package for space-constrained designs. Verify that the TTL output levels match the downstream logic requirements.

Part Context

The MAX913 is part of the MAX912/MAX913 family of high-speed, low-power comparators. While the MAX912 offers dual channels with independent latch controls, the MAX913 provides a single channel solution. Both devices share identical performance metrics regarding speed, power, and input stability, making them suitable for similar high-performance analog-to-digital interface applications.

Replacement Considerations

The MAX913 is documented as an improved plug-in replacement for the LT1016, providing significantly wider input voltage range and equivalent speed at a fraction of the power.
