MAX912CPE+

Overview

The MAX912CPE+ is a dual, high-speed, 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. It includes independent latch controls for Comparator A and B. The input common-mode range extends below the negative rail to -5.2V (at ±5V supplies). Key electrical parameters include an input offset voltage of 0.8mV typ, 110dB CMRR, and operation within the 0°C to +70°C temperature range in a 16-pin Plastic DIP package.

Feature Summary

• Ultra-fast propagation delay with stable linear region performance eliminating oscillation without hysteresis
• Independent latch control functionality for each comparator channel
• Wide common-mode input range extending below the negative supply rail
• Low power consumption compatible with single +5V or dual ±5V supply architectures

Applications

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

Procurement Notes

Verify the specific suffix 'CPE+' indicates the commercial temperature range and lead-free status against the manufacturer's current ordering guide. Confirm the 16-pin Plastic DIP package dimensions match the design constraints. Ensure the component source is authorized to guarantee authenticity and traceability for this legacy part number.

Selection Notes

Select this component when precise timing resolution is required without adding external hysteresis that degrades accuracy. The dual configuration allows independent latch control, suitable for holding signal states during sampling. Verify that the 10ns propagation delay meets system bandwidth requirements and that the 6mA supply current fits the thermal budget.

Part Context

This part belongs to the MAX912/MAX913 family of ultra-fast comparators designed for high-speed, low-power applications. The MAX912 provides dual channels while the MAX913 offers a single channel. Both share identical electrical characteristics and stability features, differing primarily in channel count and pinout configuration within the same package families.

Replacement Considerations

The datasheet identifies the MAX913 as an improved plug-in replacement for the LT1016, offering wider input voltage range and equivalent speed at lower power. No other direct cross-references are provided in the documentation.
