MP7748SGF-Z

Overview

The MP7748SGF-Z is a stereo Class-D audio amplifier manufactured by Monolithic Power Systems. It operates within a supply voltage range of 9.5 V to 36 V and delivers up to 60 W into an 8-ohm load in mono configuration, or 30 W per channel into a 4-ohm load in stereo mode. The device features a maximum output current of 4.5 A and maintains a THD+N of 0.02%. It supports both single-ended outputs and dual-channel operation, with a shutdown feature for power management. The component is housed in a 28-TSSOP-EP package and functions reliably across temperatures from -40°C to +125°C junction temperature.

Feature Summary

• Delivers high-efficiency stereo audio amplification using Class-D topology
• Configurable for either mono or stereo output channels
• Includes integrated protection mechanisms such as short-circuit protection
• Features pop-and-click suppression to minimize audible noise during startup

Applications

• High-fidelity home audio systems
• Portable speaker designs requiring efficient power usage
• Automotive infotainment audio amplifiers
• Professional PA system subwoofer drivers

Procurement Notes

Verify the specific suffix 'SGF-Z' against the manufacturer's latest datasheet to confirm pinout compatibility and thermal pad requirements. Ensure that the ordering quantity aligns with the standard factory packaging specifications provided by Monolithic Power Systems. Cross-reference the RoHS compliance status and moisture sensitivity level before finalizing procurement orders to meet assembly line standards.

Selection Notes

Select this component when designing systems requiring high output power density within a compact footprint. The wide input voltage range allows flexibility in power supply design for various battery or mains-operated applications. Consider the thermal performance of the exposed pad package when determining heat dissipation strategies for enclosed enclosures or high ambient temperature environments.

Part Context

This part belongs to the MP7748 series of audio amplifiers from Monolithic Power Systems. The series is designed for applications demanding high efficiency and low distortion. The MP7748SGF-Z specifically denotes the surface-mount variant with the TSSOP-EP package, distinguishing it from other package options within the same functional family.

Replacement Considerations

The MP7748DF-LF-Z is identified as a related product within the same manufacturer's portfolio. However, it is marked as not recommended for new designs. Verify if the MP7748SGF-Z serves as the active replacement for legacy projects previously utilizing discontinued variants.
