Dual/Quad Power Amplifier - STA540

Dual/Quad Power Amplifier - STA540

The 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 breakout board for the L298N isn't designed for it specifically, it will breakout out all pins of the STA540 to a more standard single row of 0.1" pitch headers. Also, keep an eye out for some upcoming amplifier products based on this chip!

It works great with the 6400BG Heatsink!
