Overview
The FAN7023M is a bridge-connected CMOS mono audio power amplifier manufactured by Fairchild Semiconductor. It delivers 1W of continuous average power to an 8Ω load with less than 0.2% THD from a 5V supply. The device operates within a wide voltage range and features low quiescent current for battery-powered applications.
Feature Summary
- Bridge-connected architecture for efficient power delivery
- CMOS technology for low power consumption
- Low total harmonic distortion performance
Applications
- Portable audio devices
- Battery-operated speakers
- Consumer electronics audio output stages
Procurement Notes
Verify the manufacturer marking on the component body matches Fairchild or onsemi branding. Confirm the package type is MSOP-8 as specified in the official datasheet. Check for date codes and lot traceability information required for quality assurance. Ensure the part number suffix 'M' corresponds to the specific tape and reel or tube packaging configuration documented by the supplier.
Selection Notes
Select this component when a single-channel mono amplifier is required for low-power audio applications. The 1W output capability into 8Ω loads makes it suitable for small speakers. Consider the 5V operating voltage requirement and the need for a bridge-tied load configuration. Evaluate thermal management needs based on the expected power dissipation in the MSOP-8 package.
Part Context
The FAN7023M belongs to the FAN702x series of audio amplifiers from Fairchild Semiconductor. This series includes variants like the FAN7021 and FAN7024, which share similar architectural features but may differ in channel count or power output specifications. The FAN7023M specifically targets mono audio applications requiring compact size and efficiency.
Replacement Considerations
Direct substitutes include the FAN7021M and FAN7024M from the same family, provided pin compatibility and electrical characteristics align with the design requirements. Verify that any replacement maintains the 1W output capability and 8Ω load support.
