LegendBreath Posted November 13, 2005 Report Share Posted November 13, 2005 Hi,Does someone have the pin-out for the STK4171??? Quote Link to comment Share on other sites More sharing options...
Guest Decade Posted November 13, 2005 Report Share Posted November 13, 2005 Hi legendBreath!Check this link:http://pdf.alldatasheet.co.kr/datasheet-pdf/view/82040/ETC/STK4171.html Quote Link to comment Share on other sites More sharing options...
LegendBreath Posted November 13, 2005 Author Report Share Posted November 13, 2005 Yeah, but, am I suppose to understand that pin out :-\ Is it the application I need to check? Sorry, kinda noob here ::) Quote Link to comment Share on other sites More sharing options...
Guest Decade Posted November 13, 2005 Report Share Posted November 13, 2005 Sorry, I'm not sure if you want what all pins mean like:pin 12: Left channel outPin 15: Right channel out ?Here is another data sheet by SANYO which is more complete and it has case outline, start count from left to right as in the data sheet 1-22 pins.Don't be confused by the data sheet, there is 8 STK amplifiers having same pinout with different ratings meaning output power, supply voltage and load impedance.These amplifiers can be replaced by one another just be sure that the supply voltage in the circuit you got dont exceed those in the data sheet and load impedance, there may be som small mods also to make it work properlyTell me if it is something you are going to build or just a repair of some audio amplifier.

LegendBreath Posted November 13, 2005 Author Report Share Posted November 13, 2005 Yeah, what I would like to know is that what the pins are for... like you said Pin 12: Out Left.And yeah, its something I want to build. Quote Link to comment Share on other sites More sharing options...
Guest Decade Posted November 13, 2005 Report Share Posted November 13, 2005 Alright! ;DWhy not just go for the circuit in the data sheet LegendBreath.By hte way forgot to send the link: http://pdf.alldatasheet.co.kr/datasheet-pdf/view/41602/SANYO/STK4181.htmlThink I saw a PCB layout somewhere just for simplicity in case you don't want to design your own PCB.

LegendBreath Posted November 13, 2005 Author Report Share Posted November 13, 2005 Help me a little bit... but what I would like is the Pin-outs... :P Like what is the pin 1, 2, 3 etc. Quote Link to comment Share on other sites More sharing options...
Guest Decade Posted November 14, 2005 Report Share Posted November 14, 2005 Pinout STK4171Pin 1: Left channel input (-)Pin 2: Left channel input (+)Pin 3: CompensationPin 4: CompensationPin 5: CompensationPin 6: MutingPin 7: CompensationPin 8: CompensationPin 9: -VccPin 10: Left channel OutputPin 11: +VccPin 12: BypassPin 13: Right channel outputPin 14: -VccPin 15: CompensationPin 16: GndPin 17: Right channel input (+)Pin 18: Right channel input (-) Quote Link to comment Share on other sites More sharing options...
LegendBreath Posted November 14, 2005 Author Report Share Posted November 14, 2005 Pinout STK4171Pin 1: Left channel input (-)Pin 2: Left channel input (+)Pin 3: CompensationPin 4: CompensationPin 5: CompensationPin 6: MutingPin 7: CompensationPin 8: CompensationPin 9: -VccPin 10: Left channel OutputPin 11: +VccPin 12: BypassPin 13: Right channel outputPin 14: -VccPin 15: CompensationPin 16: GndPin 17: Right channel input (+)Pin 18: Right channel input (-)Eh eh thanks alot! But, what is compensation... and for the second output of the channels, it's the ground right? And... why is there two -Vcc Quote Link to comment Share on other sites More sharing options...
Guest Decade Posted November 14, 2005 Report Share Posted November 14, 2005 Hi!STK4171 is a two channel chipamp and why the have two -Vcc.. I don't know :) in the application circuit they are tied together but there is probably a reason, I know that audioguru probably got an very good answer on that.I like to hand over the compensation question to someone else to :)and for the second output of the channels, it's the ground right?Don't know what you mean 10 & 13 is output not ground.

LegendBreath Posted November 14, 2005 Author Report Share Posted November 14, 2005 Don't know what you mean 10 & 13 is output not ground.Errmmm... you know, in audio you always have 3 (4) wires (when its stereo) well the third one, is it the GND?BTW: Is 42VDC is enough for this chip...Another BTW: The 2 channels INPUT, what happens if I put the - on the + and the + on the -? (In other words, if I inverse them...)Another BTW2: Yeah, does someone wants to explain or have somekind of tutorial on the Compensation thing...? I know one meaning of that word, something that is given for a loss or damage...Another BTW3: What is the muting and how does it works?
