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.<\/p>\n<p>This chip comes in a staggered-lead Multiwatt-15 package. While our breakout board for the L298N isn\u2019t designed for it specifically, it will breakout out all pins of the STA540 to a more standard single row of 0.1&#8243; pitch headers. Also, keep an eye out for some upcoming amplifier products based on this chip!<\/p>\n<p>It works great with the 6400BG Heatsink!<\/p>\n<p><strong>Features:<\/strong><\/p>\n<ul>\n<li>High output power capability<\/li>\n<li>Standby function (CMOS compatible)<\/li>\n<li>Minimum external components count:\n<ol>    no bootstrap capacitors<\/ol>\n<ol>    no Boucherot cells<\/ol>\n<ol>    internally fixed gain 20 dB<\/ol>\n<\/li>\n<li>No audible pop during standby operations<\/li>\n<li>Diagnostic facilities:\n<ol>    clip detector<\/ol>\n<ol>    output to GND short-circuit detector<\/ol>\n<ol>    output to VS short-circuit detector<\/ol>\n<ol>    soft short-circuit check at turn-on<\/ol>\n<ol>    thermal shutdown warning<\/ol>\n<\/li>\n<li>Output AC\/DC short circuit protection<\/li>\n<li>Soft short-circuit check at turn-on<\/li>\n<li>Thermal cutoff\/limiter to prevent chip from overheating<\/li>\n<\/ul>\n<p><strong>Don Luc<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>SparkFun: COM-09557 Description: The STA540 from STMicro is a 4-channel, class AB audio amplifier designed for high quality sound applications.
