Overview
The MP7751GF-Z is a stereo bridge-tied load (BTL) Class-D audio amplifier manufactured by Monolithic Power Systems. It delivers 20 W of output power per channel into an 8-ohm load, operating within a supply voltage range of 5 V to 26 V. The device features a total harmonic distortion plus noise (THD+N) of 0.08% and a fixed gain of 36 dB. It utilizes analog inputs and includes a shutdown function for power management. The component operates reliably across a temperature range of -40°C to +125°C and is housed in a TSSOP-28 surface-mount package.
Feature Summary
- Stereo BTL Class-D architecture providing dual-channel high-fidelity audio amplification
- Integrated shutdown control mechanism for efficient power management
- Analog input interface with fixed 36 dB gain configuration
Applications
- Portable multimedia devices requiring compact stereo audio solutions
- Home entertainment systems utilizing Class-D amplification
- Automotive infotainment audio channels
Procurement Notes
Verify the specific suffix designation when ordering, as variations such as GF-Z indicate particular packaging or environmental compliance attributes. Confirm that the required thermal performance aligns with the TSSOP-28 package capabilities for your intended application environment. Ensure compatibility with the specified 5 V to 26 V supply rails during system design validation.
Selection Notes
Select this component for applications demanding high efficiency and low distortion in a stereo configuration. The fixed 36 dB gain simplifies circuit design by reducing external component count. Consider the thermal dissipation requirements associated with 20 W per channel outputs when designing the PCB layout for adequate heat spreading.
Part Context
This part belongs to the MP7751 series of audio amplifiers from Monolithic Power Systems. The series focuses on delivering high-power audio performance in compact packages suitable for space-constrained electronic designs. The GF-Z suffix typically denotes specific manufacturing lot or packaging details consistent with MPS distribution standards.
Replacement Considerations
Consult official MPS documentation for verified cross-reference part numbers. Direct replacements must match the Class-D topology, stereo BTL configuration, and compatible supply voltage ranges.
