FAN7023MX

Overview

The FAN7023MX is a single-channel (mono) Class AB audio power amplifier manufactured by Fairchild Semiconductor, now part of onsemi. It is designed to deliver 1W of continuous average output power into an 8Ω load. The device operates within a supply voltage range of 2.2V to 5.5V and features a gain of 65dB. It utilizes an 8-pin SOP package with a terminal pitch of 1.27mm. The operational temperature range extends from -40°C to +85°C.

Feature Summary

• Bridge-connected architecture for efficient power delivery
• CMOS technology implementation for low power consumption
• Single-channel mono configuration

Applications

• Portable audio devices
• Small speaker systems
• Battery-powered consumer electronics

Procurement Notes

Verify the manufacturer designation as onsemi due to the acquisition of Fairchild Semiconductor. Confirm the specific suffix MX corresponds to the standard SOP-8 packaging and tape-and-reel or cut-tape availability options. Ensure compliance with RoHS directives if required for your assembly process. Cross-reference the datasheet revision date to ensure technical accuracy regarding electrical characteristics.

Selection Notes

Select this component when a low-voltage, single-channel audio solution is required for 8Ω loads. The 2.2V minimum operating voltage makes it suitable for battery-operated applications where power efficiency is critical. Consider the 1W power rating relative to the specific acoustic requirements of the target enclosure. The SOP-8 package facilitates surface-mount assembly in compact designs.

Part Context

This component belongs to the FAN7023 series of CMOS mono power amplifiers. It is functionally related to variants such as FAN7024, which may offer different pinouts or performance characteristics. The series is characterized by its ability to drive speakers directly without external coupling capacitors in bridge mode.

Replacement Considerations

Direct substitutes include other 1W mono Class AB amplifiers in SOP-8 packages. Verify compatibility with existing PCB footprints and thermal management requirements. Check if alternative parts support the same 2.2V to 5.5V supply range and 65dB gain specification.
