MAX913ESA+T

Overview

The MAX913ESA+T is a single-channel, ultra-fast, low-power precision TTL comparator manufactured by Analog Devices Inc. (Maxim Integrated). It features differential inputs and complementary TTL outputs with a typical propagation delay of 10ns. The device operates from a single +5V or dual ±5V supply, drawing 6mA per comparator at +5V. Key electrical parameters include an input offset voltage of 0.8mV typ, a common-mode rejection ratio of 110dB, and a power-supply rejection ratio of 100dB. It supports an extended input voltage range that includes the negative rail.

Feature Summary

• Ultra-fast response with 10ns typical propagation delay
• Stable operation in the linear region without oscillation
• Low power consumption with no minimum input slew-rate requirement
• Integrated TTL-compatible latch function for output state holding

Applications

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

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm the 'E' grade designation ensures the -40°C to +85°C operating temperature range. Ensure compatibility with standard SOIC-8 footprints during PCB layout. Cross-reference datasheet revisions to confirm pinout consistency.

Selection Notes

Select this component for high-speed applications requiring precise threshold detection with minimal power draw. The integrated latch feature simplifies timing control in sampling circuits. Consider the wide common-mode input range for signals extending below ground. Verify that the complementary TTL outputs meet the logic interface requirements of the downstream circuitry.

Part Context

This part belongs to the MAX912/MAX913 family of high-speed comparators. The MAX913 serves as a single-channel variant, while the MAX912 offers dual channels with independent latch controls. These devices are designed as improved replacements for older comparators like the LT1016, offering wider input ranges and equivalent speed at lower power levels.

Replacement Considerations

The MAX913 is documented as an improved plug-in replacement for the LT1016.
