CMP402GS

Comparators Overview

The CMP402GS is a quad low-voltage comparator from Analog Devices, housed in a 16-lead narrow SOIC package. It features a typical propagation delay of 65 ns with a 20 mV overdrive at 25°C. The device utilizes separate analog and digital supply rails, allowing the input stage to operate between +3 V and ±6 V, while the output logic interfaces with 3 V or 5 V systems. It supports an extended industrial temperature range from –40°C to +125°C.

Comparators Feature Summary

• Features independent analog and digital power supplies for flexible voltage interfacing
• Provides fast signal response with specified propagation delays
• Supports wide common-mode input voltage ranges across various supply configurations

Comparators Applications

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

Comparators Procurement Notes

Verify the specific suffix 'GS' corresponds to the 16-lead Narrow-SOIC package option when sourcing. Confirm that the required propagation delay specifications align with the 65 ns characteristic of the CMP402 variant rather than the faster CMP401 model. Ensure design compatibility with the separate analog and digital supply requirements defined in the datasheet.

Comparators Selection Notes

Select this component when designing portable instrumentation requiring interface to both 3 V and 5 V logic levels. The separate supply architecture allows optimization of input sensitivity versus output drive strength. Consider the 65 ns propagation delay against system timing requirements compared to the 23 ns alternative.

Comparators Part Context

This part belongs to the CMP401/CMP402 family of low-voltage comparators manufactured by Analog Devices. The CMP402 variant is distinguished by its 65 ns propagation delay, whereas the CMP401 offers a faster 23 ns delay. Both share identical pinouts and packaging options, differing primarily in switching speed characteristics.

Comparators Replacement Considerations

The CMP401GS serves as a high-speed substitute within the same package if faster switching is required. For TSSOP packaging needs, the CMP402GRU provides equivalent electrical performance in a different form factor.
