MAX942CSA+

Comparators Overview

The MAX942CSA+ is a dual high-speed, low-power comparator optimized for 3V and 5V single-supply systems. It features rail-to-rail inputs extending beyond supply rails and outputs that pull to within 0.4V of either rail without external pullups. The device operates from 2.7V to 5.5V with a typical propagation delay of 80ns at 5mV overdrive and a supply current of 350μA per comparator. It includes internal hysteresis for clean switching and CMOS/TTL-compatible outputs.

Comparators Feature Summary

• Rail-to-rail input voltage range extending beyond power-supply rails
• Internal hysteresis ensures clean output switching without external resistors
• CMOS and TTL logic compatible outputs requiring no external pullup circuitry

Comparators Applications

• Threshold detectors and discriminators
• Zero-crossing detectors
• Sampling circuits
• Line receivers

Comparators Procurement Notes

Verify the specific suffix 'CSA+' against the manufacturer's official ordering information to confirm the package type (SOIC-8) and temperature range (0°C to +70°C). Ensure compatibility with the required supply voltage range of 2.7V to 5.5V and check for any recent product lifecycle changes or obsolescence notices directly from Analog Devices documentation.

Comparators Selection Notes

Select this component when a dual-channel comparator is needed for portable or battery-powered equipment operating on 3V or 5V supplies. It is suitable for applications requiring fast response times and low power consumption. Consider the MAX941 if latch enable or shutdown functionality is required, or the MAX944 for quad-channel integration.

Comparators Part Context

The MAX942CSA+ belongs to the MAX941/MAX942/MAX944 family of high-speed comparators manufactured by Analog Devices/Maxim Integrated. This series is designed for systems powered from 3V or 5V supplies, combining high speed with low power consumption. The MAX942 specifically provides two independent channels in an 8-pin package.

Comparators Replacement Considerations

Direct substitutes include other members of the MAX94x family such as the MAX941ESA+ (single channel with latch/shutdown) or MAX944ESA+ (quad channel), provided pinout and functional requirements align.
