{"product_id":"pl4-com-09557","title":"Dual\/Quad Power Amplifier - STA540","description":"\u003cp\u003eThe STA540 from STMicro is a 4-channel, [class AB](http:\/\/en.wikipedia.org\/wiki\/Electronic_amplifier#Class_B_and_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.\u003c\/p\u003e  \n\n \u003cp\u003eThis chip comes in a staggered-lead Multiwatt-15 package. While our [breakout board](http:\/\/www.sparkfun.com\/commerce\/product_info.php?products_id=9540) 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!\u003c\/p\u003e  \n\n \u003cp\u003eIt works great with the 6400BG Heatsink!\u003c\/p\u003e\n\n\u003cp\u003e**Features:**\u003c\/p\u003e\n\n\u003cp\u003e* High output power capability\u003cbr\u003e\n* Standby function (CMOS compatible)\u003cbr\u003e\n* Minimum external components count: \u003cbr\u003e\n    * no bootstrap capacitors\u003cbr\u003e\n    * no Boucherot cells\u003cbr\u003e\n    * internally fixed gain 20 dB\u003cbr\u003e\n* No audible pop during standby operations\u003cbr\u003e\n* Diagnostic facilities: \u003cbr\u003e\n    * clip detector\u003cbr\u003e\n    * output to GND short-circuit detector\u003cbr\u003e\n    * output to VS short-circuit detector\u003cbr\u003e\n    * soft short-circuit check at turn-on\u003cbr\u003e\n    * thermal shutdown warning\u003cbr\u003e\n* Output AC\/DC short circuit protection\u003cbr\u003e\n* Soft short-circuit check at turn-on\u003cbr\u003e\n* Thermal cutoff\/limiter to prevent chip from overheating\u003c\/p\u003e\n\n\u003cp\u003e**Documents:**\u003c\/p\u003e\n\n\u003cp\u003e* [Datasheet](http:\/\/www.sparkfun.com\/datasheets\/Components\/General\/STA540.pdf)\u003c\/p\u003e","brand":"PuriLite","offers":[{"title":"Default Title","offer_id":39705321963701,"sku":"PL4-COM-09557","price":21.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/09557-Dual_Quad_Power_Amplifier_-_STA540-01.jpg?v=1618236929","url":"https:\/\/getcahits.com\/products\/pl4-com-09557","provider":"PuriLite","version":"1.0","type":"link"}
