MAX913CSA+

Overview

The MAX913CSA+ is a single-channel, ultra-fast, 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. Key electrical parameters include an input offset voltage of 0.8mV, a common-mode rejection ratio of 110dB, and a power-supply rejection ratio of 100dB. It supports an extended input voltage range that includes the negative rail and functions within a commercial temperature range of 0°C to +70°C in an 8-pin SO package.

Feature Summary

• Ultra-fast response with 10ns typical propagation delay for high-speed signal processing
• Stable operation in the linear region without oscillation, eliminating the need for hysteresis
• Low power consumption with extremely low supply current requirements
• 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 CSA+ against the manufacturer's ordering information to confirm the commercial temperature range and SOIC-8 package configuration. Ensure compatibility with existing board layouts regarding pin assignments and thermal dissipation limits. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high-speed comparison with minimal power draw. It serves as an improved plug-in replacement for the LT1016, offering a wider input voltage range and equivalent speed at lower power. Consider the MAX912 if dual channels are required, noting it includes independent latch controls while maintaining equal performance characteristics.

Part Context

The MAX913 belongs to the Maxim Integrated high-speed comparator family, designed for precision analog-to-digital conversion interfaces and timing circuits. It utilizes a bipolar process with 154 transistors. The device integrates a unique design preventing linear region oscillation, distinguishing it from standard comparators like the industry-standard 686 which may require external hysteresis for stability.

Replacement Considerations

The MAX913 is documented as an improved plug-in replacement for the LT1016, providing significantly wider input voltage range and equivalent speed at a fraction of the power.
