20W双声道功放MP7748DF

The MP7748 is a Class-D Audio Amplifier for driving stereo speakers in single-ended configuration or a mono speaker in bridge-tied-load configuration. It is fully integrated audio amplifier which dramatically reduces solution size by integrating the following:
• 250mΩ power MOSFETs
• Start-up/shut-down pop elimination
• Short circuit protection circuits





• Output Power at 24V VDD and 10% THD+N
• Stereo SE Configuration: 20W per Channel into 4Ω Load
• Mono BTL Configuration: 50W into 6Ω Load
• THD+N = 0.02% at 1W, 8Ω(SE)
• Low Noise (103μV with SE Configuration, 140μV with BTL Configuration)
• Switching Frequency Up to 1MHz
• 9.5V to 36V Operation from a Single Supply
• Integrated Startup and Shutdown Pop Elimination Circuit
• Programmable UVP
• Thermal and Short Circuit Protection
• Integrated Power FETs
• Available in TSSOP28-Exposed Package
