MAT04FY

Overview

The MAT04FY is a monolithic matched quadruplet transistor array manufactured by Analog Devices Inc. It integrates four high-performance NPN bipolar junction transistors on a single silicon die to ensure exceptional matching characteristics. Key electrical parameters include a collector current (IC) of 1 mA, a DC current gain (hFE) range of 100 to 200, and a low input offset voltage (VOS) typically less than 50 µV at room temperature. The device features a tight base-emitter voltage matching (ΔVBE) of 0.5 mV maximum and operates within a junction temperature range of -55°C to +125°C. Packaged in an 8-lead DIP or SOIC format, it is designed for precision analog applications requiring stable thermal tracking.

Feature Summary

• Monolithic integration of four matched NPN transistors on a single die for superior thermal tracking
• Ultra-low input offset voltage and tight base-emitter voltage matching for high precision
• High DC current gain consistency across all four devices within the array

Applications

• Precision instrumentation amplifiers
• Low-offset operational amplifier input stages
• High-accuracy current mirrors and sources
• Precision rectifier circuits

Procurement Notes

Verify the specific suffix 'FY' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for both DIP and surface-mount variants. Cross-reference lot codes for traceability requirements in regulated industries.

Selection Notes

Select this component when precise matching between multiple transistors is critical for circuit performance. Consider the thermal coupling inherent in the monolithic design for applications sensitive to temperature gradients. Evaluate the required hFE binning if strict gain matching is necessary beyond the standard specification.

Part Context

The MAT04 series represents Analog Devices' high-precision matched transistor arrays. The FY suffix typically denotes a specific package configuration, often related to the industrial temperature grade or physical footprint. This family is widely used in professional audio, medical instrumentation, and test equipment where signal integrity depends on component matching.

Replacement Considerations

Direct replacements include other matched quad arrays such as the LM394 or MC1404, though pinouts and specific VOS values may differ. Verify that substitute components offer comparable ΔVBE and thermal tracking capabilities to maintain circuit accuracy without redesigning the bias network.
