FAN7024MUX

Overview

The FAN7024MUX is a high-performance, single-channel (mono) Class AB audio amplifier integrated circuit manufactured by Fairchild Semiconductor. It delivers 675mW of continuous average power to an 8Ω load with less than 0.3% Total Harmonic Distortion (THD). The device operates from a supply voltage range of 2.3V to 5.5V and features a shutdown function for power management. Designed for compact applications, it is housed in an 8-MSOP package and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Delivers 675mW output power to an 8Ω load with low distortion
• Operates on a wide supply voltage range from 2.3V to 5.5V
• Includes a dedicated shutdown pin for efficient power control
• Compact 8-MSOP surface-mount package design

Applications

• Portable audio devices requiring mono amplification
• Battery-powered consumer electronics
• Compact speaker systems in mobile gadgets

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor assets are now managed by ON Semiconductor. Confirm the specific suffix 'MUX' corresponds to the 8-MSOP package variant. Check for RoHS compliance status and ensure the component is sourced from authorized distributors to avoid counterfeit parts. Validate the active product status before procurement.

Selection Notes

Select this component for mono audio applications where space is limited and low voltage operation is required. It is suitable for designs needing moderate power output into 8Ω loads without external heat sinking. Consider the 8-MSOP footprint for PCB layout constraints. Ensure the supply voltage remains within the 2.3V to 5.5V range for optimal performance.

Part Context

The FAN7024 series belongs to Fairchild's line of CMOS audio power amplifiers. The MUX suffix specifically denotes the 8-lead MSOP package configuration. This family targets portable audio markets, offering a balance between power efficiency and sound quality in a small form factor.

Replacement Considerations

Check for direct pin-compatible substitutes such as the FAN7024MU if different packaging is acceptable. Verify electrical specifications match for any cross-brand replacements.
