CMP04FS

Comparators Overview

The CMP04FSZ is a quad low power precision comparator in a 14-lead SOIC package. It features high gain (200 V/mV typ), low offset voltage (1 mV max), and low input bias current (100 nA max). The device supports single or dual supply operation with an input voltage range including ground. It offers open-collector outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic families.

Comparators Feature Summary

• Four independent precision comparators with high gain and low offset voltage
• Low power consumption of 1.5 mW per comparator
• Open-collector output compatible with multiple logic families
• Input voltage range includes ground for single-supply applications

Comparators Applications

• Threshold detection circuits
• Zero crossing detectors
• Window detectors
• Analog interfaces for microprocessor systems

Comparators Procurement Notes

Verify the ordering suffix Z indicates RoHS compliance. Confirm the package type matches the required 14-Lead Standard Small Outline Package (R-14). Ensure the temperature range meets the application requirements of -40°C to +85°C. Check for any specific handling precautions related to electrostatic discharge sensitivity.

Comparators Selection Notes

Select this component for applications requiring low power consumption and high precision. Consider the open-collector output when designing pull-up resistor networks for different logic levels. Evaluate the input common-mode voltage range to ensure compatibility with the signal source. Verify that the supply voltage does not exceed the absolute maximum ratings.

Comparators Part Context

The CMP04FSZ belongs to the CMP04 family of quad comparators from Analog Devices Inc. It is designed as a direct replacement for LM139/LM239/LM339 comparators. The device integrates four independent comparators on a single chip, offering a compact solution for precision analog signal processing tasks.

Comparators Replacement Considerations

The datasheet states it directly replaces LM139/LM239/LM339 comparators. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same temperature and supply voltage requirements.
