Overview
The MP7748SGF-P is a stereo Class-D audio amplifier manufactured by Monolithic Power Systems. It delivers 30W per channel into a 6-ohm load with single-ended output or 60W in mono BTL configuration. The device operates on a supply voltage range of 9.5V to 36V and supports a maximum output current of 4.5A. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.02% and a quiescent current of 3mA. It features a shutdown mode for power management and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Stereo Class-D architecture providing high-efficiency audio amplification
- Supports both single-ended stereo and bridged-tied load mono configurations
- Integrated thermal protection and shutdown functionality
Applications
- Home theater systems
- Portable speakers
- Audio amplifiers
Procurement Notes
Verify the specific suffix against official MPS documentation, as the provided model includes 'P' which may indicate packaging variations distinct from the standard 'Z' suffix found in public catalogs. Confirm RoHS compliance status and moisture sensitivity levels directly with the manufacturer before integration. Ensure the component matches the required TSSOP-F-28 package dimensions for your PCB layout.
Selection Notes
Select this component when designing stereo audio systems requiring up to 30W per channel at 6 ohms. It is suitable for applications needing low THD+N performance and wide supply voltage compatibility. Consider the TSSOP-F-28 package size for space-constrained designs. Verify that the input voltage range aligns with your system's power supply rails.
Part Context
This part belongs to the MP7748 series of Class-D audio amplifiers from Monolithic Power Systems. The series includes variants like the MP7748DF, which offers 20W stereo output. The MP7748S datasheet confirms the family's capability for 2x30W stereo or 60W mono operation. These devices are designed for high-efficiency audio applications.
Replacement Considerations
The MP7748DF-LF-Z is listed as a related product but provides lower power output (20W stereo). No direct public substitute with identical 30W specs is confirmed in the available data. Check MPS for newer equivalents if the MP7748SGF-P is obsolete.
