MP7770 2 x 45W Stereo Single-Ended or 90W Mono BTL Class-D Audio Amplifier The Future of Analog IC Technology DESCRIPTION FEATURES MP7770 is an analog class-D audio amplifier 9.5V-to-36V Operation from a Single Supply that can drive either stereo speakers in single- 8.5A Peak Current Output ended configuration or a mono speaker in a Output Power at 36V and 10%THD: bridge-tied-load configuration. It is part of - Stereo Single-Ended: 2 x 45W into 4 Load, MPSs family of fully-integrated audio amplifiers - Bridge-Tied Load: 90W into 8 Load that dramatically reduce footprint size by THD+N = 0.03% at 1W, 8 integrating: > 90% Efficiency at 10%THD Low Noise 100m power MOSFETs Switching Frequency of up to 1MHz Startup/Shutdown pop elimination Integrated Startup and Shutdown Pop Elimination Circuit Short-circuit protection circuits Programmable UVP The MP7770 is capable of delivering 45W per Thermal and Short-Circuit Protection channel into 4 speaker in single-ended output Output Fault Flag and Thermal Warning structure, or delivering 90W into 8 speaker in Integrated Power FETs bridge-tied-load output structure under 36V TSSOP28-EP Package with Exposed Pad VDD. MPSs class D audio amplifiers exhibit the high fidelity of a Class A/B amplifier at higher APPLICATIONS efficiencies. The circuit is based on the MPSs DVD Receiver proprietary variable-frequency topology, which Mini Combo System delivers excellent linearity, fast response time Home Theater Systems and operates from a single power supply.
