3. AUDIO AMPLIFIER STAGE WITH MP7722
3.1. General Description
17MB35 uses a 20W Class D Stereo Single Ended Audio Amplifer for audio. The
MP7722 is a stereo 20W Class D Audio Amplif
ier. It is one of MPS’ second generation of
fully integrated audio amplifiers which dramatically reduces solution size by integrating
the following:
x 180mSRZHU026)(7V
x Startup / Shutdown pop elimination
x Short circuit protection
x Mute / Standby
The MP7722 utilizes a single ended output structure capable of delivering 2 x 20W into
4 speakers. MPS Class D Audio Amplifiers exhibit the high fidelity of a Class A/B
amplifier at efficiencies greater than 90%. The circuit is based on the MPS’ proprietary
variable frequency topology that delivers low distortion, fast response time and operates
on a single power supply.
3.2. Features
x 2 x 20W Output at VDD = 24V into a 4ORDG
x THD+N = 0.06% at 1W, 8
x 93% Efficiency at 20W
