MAX912ESE-T

Overview

The MAX912ESE-T is a dual, high-speed, low-power precision 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), an input bias current of 8µA, and a common-mode input range extending below the negative rail. It is housed in a 16-pin Narrow SO package.

Feature Summary

• Ultra-fast operation with minimal propagation delay for high-speed signal processing
• Stable linear region performance eliminates output instability during slow-moving input signals
• Integrated latch function allows holding the comparator output state via TTL-compatible control pins
• Wide common-mode input range extends below the negative supply rail for flexible interfacing

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm the 'E' designation corresponds to the extended temperature range of -40°C to +85°C. Ensure the narrow SOIC-16 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring high speed combined with low power consumption under a single +5V supply. The dual-channel architecture provides independent latch controls for each comparator, suitable for precise timing applications. Consider the wide input voltage range if the signal source exceeds standard logic levels relative to the negative rail.

Part Context

This part belongs to the MAX912/MAX913 family of ultra-fast, low-power precision TTL comparators. The MAX912 serves as the dual-channel variant, offering equal performance to the single-channel MAX913 while adding independent latch controls. It is designed as an improved replacement for legacy comparators like the LT1016, providing wider input voltage ranges at lower power dissipation.

Replacement Considerations

The MAX913 is documented as an improved plug-in replacement for the LT1016. For direct dual-comparator replacements, verify pin compatibility with existing designs utilizing similar high-speed comparator architectures.
