CMP402GS-REEL

Comparators Overview

The CMP402GS-REEL is a quad comparator from Analog Devices, packaged in a 16-lead Narrow-SOIC (R-16A). It features a propagation delay of 65 ns at 25°C with a 20 mV overdrive. The device supports single-supply operation and separate analog/digital supplies, allowing the input stage to operate from +3 V to ±6 V while the output logic accepts 3 V or 5 V. It operates within an extended industrial temperature range of –40°C to +125°C.

Comparators Feature Summary

• Features separate analog and digital supply sections for flexible voltage interfacing
• Supports wide input common-mode ranges extending to negative voltages
• Provides fast propagation delay suitable for high-speed signal processing
• Compatible with standard 3 V and 5 V logic families

Comparators Applications

• Battery-operated instrumentation
• Line receivers
• Level translators
• Read channel detection

Comparators Procurement Notes

Verify that the ordering suffix GS corresponds to the 16-Lead SOIC package type as specified in the official Analog Devices ordering guide. Confirm the component meets the required extended industrial temperature specifications before integration into the design.

Comparators Selection Notes

Select this model when independent analog and digital power domains are necessary to interface low-voltage sensors with higher-voltage logic systems. The CMP402 offers a slower propagation speed compared to the CMP401 variant, which may be advantageous for reducing electromagnetic interference in specific circuit topologies.

Comparators Part Context

This component belongs to the CMP401/CMP402 family of low-voltage comparators manufactured by Analog Devices. While sharing identical packaging and general architecture, the CMP402 is distinguished by its 65 ns propagation delay, contrasting with the 23 ns delay found in the CMP401 counterpart.

Comparators Replacement Considerations

CMP401GS-REEL serves as a functional substitute offering faster switching speeds within the same package.
