Overview
The MP7751GF-P is a stereo Class-D audio amplifier manufactured by Monolithic Power Systems. It operates within a supply voltage range of 5 V to 26 V and delivers 20 W per channel into an 8-ohm load. The device features a fixed switching frequency, a gain of 36 dB, and a total harmonic distortion plus noise of 0.08%. It includes a shutdown function and draws 130 uA in standby. The component is housed in a TSSOP-EP-28 package and supports operation from -40°C to +125°C.
Feature Summary
- Stereo BTL Class-D architecture for high-efficiency audio amplification
- Integrated shutdown mode for power management
- Low total harmonic distortion plus noise performance
Applications
- Audio systems requiring stereo amplification
- Portable electronic devices with battery power constraints
- Consumer electronics utilizing Class-D topology
Procurement Notes
Verify the specific suffix GF-P against the manufacturer's current datasheet to confirm pinout and thermal pad configuration. Confirm that the TSSOP-EP-28 package matches your PCB footprint requirements. Check for any recent lifecycle status updates or alternative recommendations from Monolithic Power Systems before finalizing procurement plans.
Selection Notes
Select this component when a dual-channel solution is required for stereo applications. Ensure the design accommodates the 5 V to 26 V input range and the 8-ohm load impedance. Consider the fixed frequency operation and thermal dissipation needs associated with the 20 W output capability in the specified package.
Part Context
This part belongs to the Monolithic Power Systems audio amplifier portfolio, specifically designed for Class-D applications. It serves as a stereo solution offering balanced left and right channel outputs. The device integrates protection features typical of modern audio ICs while maintaining a compact form factor suitable for space-constrained designs.
Replacement Considerations
Consult official MPS documentation for direct cross-references. Verify compatibility regarding package dimensions, pin assignments, and electrical specifications if substituting with other Class-D stereo amplifiers.
