MAX913CPA+

Overview

The MAX913CPA+ is a single-channel, ultra-fast, low-power precision comparator manufactured by Analog Devices Inc. (Maxim Integrated). It features differential inputs and complementary TTL outputs, designed for high-speed applications with minimal power consumption. The device operates from a single +5V supply or dual ±5V supplies, offering a wide common-mode input 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 Plastic DIP package.

Feature Summary

• Ultra-fast response with a typical propagation delay of 10ns
• Low power consumption suitable for battery-operated systems
• Stable operation in the linear region without oscillation
• Wide common-mode input range extending 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 'CPA+' to confirm the commercial temperature range (0°C to +70°C) and 8-pin PDIP packaging. Ensure compatibility with existing board layouts requiring through-hole mounting. Confirm that the single-channel configuration meets system requirements, as the dual-channel MAX912 offers similar performance with latch controls. Check for RoHS compliance documentation if required by local regulations.

Selection Notes

Select the MAX913CPA+ when a single comparator channel is sufficient for high-speed signal processing. It serves as an improved plug-in replacement for the LT1016, offering wider input voltage range and equivalent speed at lower power. Consider the MAX912 variant if dual channels or independent latch controls are needed. Ensure the application does not require extended industrial temperature ranges, which would necessitate the 'E' suffix version.

Part Context

The MAX913 belongs to the Maxim Integrated family of high-speed, low-power comparators. It is part of a series that includes the dual-channel MAX912. These devices are designed to address the instability issues found in many high-speed comparators when operating in their linear region. The MAX913 specifically targets applications requiring fast response times and low power dissipation in standard TTL logic environments.

Replacement Considerations

The datasheet identifies the MAX913 as an improved plug-in replacement for the LT1016.
