MAX912ESE

Overview

The MAX912ESE 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. It offers a wide common-mode input range extending below the negative rail and includes independent latch controls for each channel. Designed for stability in the linear region without hysteresis, it supports applications requiring fast response and low power consumption.

Feature Summary

• Ultra-fast propagation delay ensures rapid signal processing
• Stable operation in the linear region eliminates output oscillation
• Integrated latch function allows state holding via dedicated control pins
• Wide common-mode input range extends below the negative supply rail

Applications

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

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the 'SE' designation corresponds to the narrow SOIC-16 package. Ensure compatibility with existing board layouts regarding pin configurations and latch enable requirements before integration.

Selection Notes

Select this component when dual-channel comparison with independent latching is required. It serves as an improved replacement for older comparators like the LT1016, offering wider input voltage ranges and equivalent speed at lower power levels. Ideal for designs needing stable performance with slow-moving input signals without adding external hysteresis.

Part Context

Part of the MAX912/MAX913 family of ultra-fast, low-power precision TTL comparators. The MAX912 provides dual channels with independent latch controls, while the MAX913 offers a single channel. Both share identical electrical performance characteristics and are designed for high-speed, low-power applications in single or dual supply systems.

Replacement Considerations

The MAX913 is documented as an improved plug-in replacement for the LT1016. For dual-channel needs, verify if the MAX912 meets the specific latch and speed requirements previously served by legacy parts.
