SparkFun Dual/Quad Power Amplifier - STA540 Audio, General ICs SMD We highly recommend using theThe STA540 from STMicro is a 4 channel, class AB audio amplifier designed for high quality sound applications. The four independent channels makes this amplifier a great choice for a number of projects, with needs ranging from four speakers stereo (F R) to two speaker bridge solutions. The chip accepts a voltage supply ranging from 8 to 22VDC and has very high output power capability. This chip comes in a staggered lead Multiwatt 15 package. While our
