MP7748DF是一个2 x 20W Stereo Single Ended Class-D AudioAmplifier
其具体应用如下 ：
Description:
The MP7748 is a Class-D Audio Amplifier for driving stereospeakers isingle-ended cofiguratioor a mono speaker inbridge-tied-load configuration. Iis fully iegrated audioamplifier which dramaticallyeduces solutiosize by iegratingthe following:
• 250mΩ power MOSFETs
• Start-up/shut-dowpop eliminatio
• Shorcircuiprotectiocircuits
The MP7748 is capable of delivering 20W per channel io 4Ω speakerisingle-ended outpustructure, or delivering 50W io 6Ω speakeribridge-tied-load outpustructure under 24V VDD. MPS Class-DAudio Amplifiers exhibithe high fidelity of a Class A/B amplifierahigh efficiencies. The circuiis based othe MPS’ proprietaryvariable frequencyopologyhadelivers excellenlinearity, fastresposeime and operates oa single power supply.
MP7748 features programmable VDD shutdowvoltage for each channelby cotrollinghe UVPode voltage. The defaulVDD shutdown(risinghreshold) voltage is 8.4V ifhe UVP piis NC. Features: • OutpuPower a24V VDD and 10% THD+N
• Stereo SE Configuration: 20W per Channel io 4Ω Load
• Mono BTL Configuration: 50W io 6Ω Load
• THD+N = 0.02% a1W, 8Ω(SE)
• Low Noise (103μV with SE Configuration, 140μV with BTLConfiguration)
• Switching Frequency Upo 1MHz
• 9.5Vo 36V Operatiofrom a Single Supply
• Iegrated Startup and ShutdowPop EliminatioCircui
• Programmable UVP
• Thermal and ShorCircuiProtectio
• Iegrated Power FETs
• Available iTSSOP28-Exposed Package 方案服务：可配合协助做方案，提供技术支持
