MAX913ESA

Overview

The MAX913ESA is a single-channel, ultra-fast, low-power precision TTL comparator manufactured by Analog Devices Inc. (formerly Maxim Integrated). It features differential inputs and complementary TTL outputs, designed for high-speed applications requiring minimal power consumption. The device operates from a single +5V supply or dual ±5V supplies, with an input common-mode range that extends below the negative rail. Key electrical specifications 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 SOIC package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Ultra-fast propagation delay of 10ns typical
• Low power consumption with 6mA supply current per comparator
• Stable operation in the linear region without oscillation
• Input range extends 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 to confirm the temperature grade and package type, as the MAX913 family includes variants such as C (commercial) and E (industrial) grades. Ensure the selected part matches the required operating temperature range for the application. Cross-reference the manufacturer's latest documentation to confirm availability and any potential pinout or functional updates compared to legacy versions.

Selection Notes

Select the MAX913ESA when a single comparator channel is sufficient for the design. Consider the MAX912 if dual channels are needed, noting it includes independent latch controls. Evaluate the need for latch functionality; if not required, ensure the Latch Enable pin is managed correctly. Verify that the 10ns propagation delay meets the system timing requirements and that the TTL output levels are compatible with downstream logic.

Part Context

The MAX913 is part of the MAX912/MAX913 family of high-speed comparators. It serves as an improved plug-in replacement for the LT1016, offering a wider input voltage range and equivalent speed at lower power. The family is characterized by its ability to operate stably in the linear region, eliminating the need for external hysteresis in many applications.

Replacement Considerations

The datasheet identifies the MAX913 as an improved plug-in replacement for the LT1016. Verify pin compatibility and electrical parameter alignment before substitution. No other direct substitute part numbers are explicitly confirmed in the provided source material.
