CMP401GS-REEL

Comparators Overview

The CMP401GS-REEL is a quad analog comparator from Analog Devices, housed in a 16-lead SOIC package. It features separate analog and digital supply sections, allowing the input stage to operate from +3 V to ±6 V while the output interfaces with 3 V or 5 V logic. The device offers propagation delays of 23 ns (CMP401) or 65 ns (CMP402), an input common-mode voltage range up to 3.9 V, and operates within an extended industrial temperature range of –40°C to +125°C.

Comparators Feature Summary

• Features independent analog and digital power supplies for flexible interface compatibility
• Provides fast switching performance with low propagation delay options
• Supports wide input common-mode voltage ranges extending into negative voltages
• Designed for low power consumption suitable for battery-operated systems

Comparators Applications

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

Comparators Procurement Notes

Verify that the ordering suffix matches the required package type, as the datasheet lists specific suffixes for surface-mount variants. Confirm the specific model variant (CMP401 vs CMP402) corresponds to the desired propagation delay characteristics. Ensure the reel packaging aligns with automated assembly requirements. Cross-reference the manufacturer part number against official distributor catalogs to confirm current availability status and compliance documentation.

Comparators Selection Notes

Select this component when interfacing between different voltage domains is required due to its separate analog and digital supply pins. Choose the CMP401 variant if faster switching speeds are critical for the application timing. Consider the wide input voltage range if signals extend below ground potential. Evaluate the power consumption profiles against battery life requirements for portable devices.

Comparators Part Context

This component belongs to the CMP401/CMP402 family of low-voltage comparators manufactured by Analog Devices. The series is designed to bridge high-speed signal processing with low-power constraints. Other members include the CMP402 with slower propagation speeds and variants in TSSOP packages, all sharing the same functional architecture of separated supply rails.

Comparators Replacement Considerations

Direct substitutes include the CMP402GS-REEL for applications tolerating higher propagation delays, or the CMP401GRU-REEL for those requiring a TSSOP package instead of SOIC. Verify pinout compatibility and electrical specifications before swapping.
