Overview
The BH7824FVM-FTR is a monaural Class-AB audio amplifier manufactured by Rohm Semiconductor. It delivers 500 mW of output power into an 8-ohm load. The device operates on a single supply voltage ranging from 1.8 V to 5.5 V. It features integrated pop-suppression and shutdown capabilities, along with thermal protection. The component is housed in an 8-pin MSOP package and supports surface-mount installation. It functions within a temperature range of -30°C to +85°C.
Feature Summary
- Monaural Class-AB architecture for efficient audio amplification
- Integrated pop-suppression circuitry to minimize startup noise
- Shutdown mode for power management and thermal protection
Applications
- Mobile phone speaker drivers
- Portable consumer electronics audio outputs
- Handheld device mono audio systems
Procurement Notes
Verify the specific suffix (FTR vs TR) as it may indicate tape-and-reel variations or packaging differences. Confirm RoHS compliance status for environmental regulations. Check lifecycle status, as this part is marked NRND (Not Recommended for New Designs). Ensure the 8-MSOP footprint matches your PCB design constraints before ordering.
Selection Notes
Select this component when a low-voltage, single-channel amplifier is required for portable devices. It is suitable for applications needing 500 mW output at 8 ohms. Consider the NRND status for long-term production viability. Compare pinout compatibility if replacing existing designs. Verify supply voltage ranges match the target system's battery specifications.
Part Context
This part belongs to the BH7824 series of audio amplifiers from Rohm Semiconductor. It is designed for mobile and consumer electronics applications requiring high performance in small packages. The series typically includes variants with different packaging or reel configurations. It serves as a solution for mono speaker driving in space-constrained portable devices.
Replacement Considerations
The LM4902MM/NOPB from Texas Instruments is listed as a similar alternative. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Ensure the replacement meets the same voltage and power requirements.
