CMP402GSZ

Comparators Overview

The CMP402GSZ is a quad low-voltage comparator from Analog Devices, featuring a typical propagation delay of 65 ns at 5V and 70 ns at 3V. It operates with separate analog and digital supplies, supporting an analog input range from -5V to +3.9V and digital outputs compatible with 3V or 5V logic. The device draws approximately 1.4mA analog current and 2.0mA digital current at 25°C. It is housed in a 16-lead narrow SOIC package and functions within an extended industrial temperature range of -40°C to +125°C.

Comparators Feature Summary

• Features independent analog and digital power supply sections for flexible voltage interfacing
• Provides fast signal processing with specified propagation delays under varying overdrive conditions
• Supports wide common-mode input voltage ranges extending into negative voltages
• Designed for low-power operation suitable for battery-driven applications

Comparators Applications

• Battery-operated instrumentation systems
• Line receiver circuits
• Voltage level translation interfaces
• Read channel detection mechanisms

Comparators Procurement Notes

Verify the specific suffix 'GSZ' indicates RoHS compliance and standard narrow SOIC packaging when sourcing. Confirm that the component meets the required extended industrial temperature specifications for your environment. Ensure proper electrostatic discharge handling procedures are followed during assembly due to device sensitivity. Cross-reference the ordering guide to confirm availability of reel options if high-volume manufacturing is planned.

Comparators Selection Notes

Select this component when separate analog and digital supply rails are necessary to isolate noise or accommodate different voltage levels. The CMP402 offers a slower propagation speed compared to the CMP401 variant, which may be advantageous for reducing electromagnetic interference in sensitive designs. Consider the 16-lead SOIC footprint for PCB layout compatibility. Evaluate the input offset voltage drift characteristics against your precision requirements across the operating temperature range.

Comparators Part Context

This part belongs to the CMP401/CMP402 family of low-voltage comparators manufactured by Analog Devices. The CMP402 variant specifically provides a 65 ns propagation delay, distinguishing it from the faster 23 ns CMP401 model. Both share identical pinouts and functional architectures but differ in switching speed specifications. The family is designed for portable instrumentation and general-purpose comparison tasks requiring low power consumption.

Comparators Replacement Considerations

The CMP401GSZ serves as a direct pin-compatible alternative offering faster 23 ns propagation delay. Other quad comparator families may require schematic modifications due to differing pin configurations or supply voltage limitations.
