MAT04AY

Overview

The MAT04AY is a high-precision quad matched NPN small-signal transistor array manufactured by Analog Devices Inc. It features a ceramic dual in-line package (CDIP) designed for applications requiring tight matching and low noise. The device operates with a collector current of 30 mA and a breakdown voltage of 40 V. It supports a wide temperature range from -55°C to +125°C, ensuring reliability in demanding environments.

Feature Summary

• Provides four matched NPN transistors within a single package for superior circuit symmetry
• Utilizes precision monolithic construction to minimize offset voltage and current variations
• Offers low noise performance suitable for sensitive analog signal processing

Applications

• Precision instrumentation amplifier input stages
• High-performance differential amplifier circuits
• Low-noise preamplifier designs

Procurement Notes

Verify the specific suffix and manufacturer documentation before procurement. Ensure the CDIP package compatibility with your PCB footprint. Confirm that the operating temperature range meets your system requirements. Check for any recent manufacturing changes or alternate sources listed in official datasheets.

Selection Notes

Select this component when matched transistor pairs are critical for minimizing offset errors. Consider the CDIP package constraints for your assembly process. Evaluate the thermal management needs given the 125°C maximum rating. Compare against other precision arrays if space or pin count differs.

Part Context

This part belongs to the MAT04 family of precision matched transistor arrays from Analog Devices. It serves as a high-reliability alternative to discrete matched pairs, offering better thermal tracking and reduced board space. The series is known for its use in high-end audio and measurement equipment.

Replacement Considerations

Public confirmed substitute part numbers include MAT-04BY/883. Verify pinout and electrical specifications match before substitution.
