FAN7023MUX

Overview

The FAN7023MUX is a bridge-connected CMOS mono audio power amplifier manufactured by Fairchild Semiconductor. It delivers 1W of continuous average output power to an 8Ω load. The device operates in Class AB topology and is housed in an 8-MSOP surface-mount package. Designed for low-voltage applications, it integrates protection features suitable for portable consumer electronics.

Feature Summary

• Bridge-connected architecture for efficient single-supply operation
• CMOS technology for low quiescent current consumption
• Integrated thermal shutdown and short-circuit protection

Applications

• Portable MP3 players
• Mobile phones
• Personal digital assistants

Procurement Notes

Verify the manufacturer marking on the component body matches Fairchild Semiconductor or onsemi branding. Confirm the suffix MUX indicates the specific tape-and-reel packaging configuration if required for automated assembly processes. Ensure the datasheet version aligns with the production batch date code.

Selection Notes

Select this component when a compact mono amplifier solution is needed for battery-powered devices requiring minimal external components. The 8-MSOP package facilitates space-constrained PCB layouts. Consider the 1W power rating relative to the speaker impedance and supply voltage constraints of the target application design.

Part Context

This part belongs to the FAN7023 series of audio amplifiers. It represents a transition from discrete solutions to integrated mono amplifiers in the Fairchild semiconductor portfolio. The device utilizes standard CMOS processes to balance performance and cost for high-volume consumer markets.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify that substitute parts maintain identical power output capabilities and package dimensions for seamless integration without redesigning the host circuit board.
