{"title":"Dual/Quad Power Amplifier - STA540","handle":"dual-quad-power-amplifier-sta540","url":"/products/dual-quad-power-amplifier-sta540","description":"   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!  Features:   High output power capability Standby function (CMOS compatible) Minimum external components count:   no bootstrap capacitors no Boucherot cells internally fixed gain 20 dB   No audible pop during standby operations Diagnostic facilities:   clip detector output to GND short-circuit detector output to VS short-circuit detector soft short-circuit check at turn-on thermal shutdown warning   Output AC/DC short circuit protection Soft short-circuit check at turn-on Thermal cutoff/limiter to prevent chip from overheating    Documents:   Datasheet  ","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13986,"title":"Default Title","sku":"SF-COM-09557","price":11.91,"on_sale":false,"in_stock":true,"available_quantity":79,"option1":"Default Title"}]}
