CMP402GRU-REEL

Comparators Overview

The CMP402GRU-REEL is a quad low-voltage comparator from Analog Devices, featuring a typical propagation delay of 65 ns. It utilizes separate analog and digital supply sections, allowing the input stage to operate from +3 V up to ±6 V while the output supports 3 V or 5 V logic levels. The device operates over an extended industrial temperature range of –40°C to +125°C and is housed in a 16-lead TSSOP package.

Comparators Feature Summary

• Features separate analog and digital power supplies for flexible interface compatibility
• Provides fast propagation delay suitable for high-speed signal processing
• Supports wide common-mode input voltage ranges extending into negative voltages

Comparators Applications

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

Comparators Procurement Notes

Verify that the specific suffix GRU corresponds to the 16-lead TSSOP package variant. Confirm the REEL designation indicates tape-and-reel packaging rather than tube distribution. Ensure the component meets the required extended industrial temperature specifications for your application environment before finalizing procurement.

Comparators Selection Notes

Select this component when independent analog and digital supply rails are necessary to optimize performance across different voltage domains. The CMP402 offers a slower propagation speed compared to the CMP401 but maintains low power consumption. Verify that the 16-lead TSSOP footprint aligns with your PCB layout constraints and thermal requirements.

Comparators Part Context

This part belongs to the CMP401/CMP402 family of low-voltage comparators designed for portable applications. While the CMP401 provides faster switching speeds, the CMP402 balances speed with power efficiency. Both variants share identical pinouts and functional architectures, differing primarily in their dynamic performance characteristics.

Comparators Replacement Considerations

The CMP402GS serves as a direct package alternative using the narrow SOIC format. Cross-reference the CMP401 if higher propagation speed is required, noting the difference in switching performance between the two models.
