tda1518 quick help needed
Hi..
I have wired up a tda1518bq chip but have problems getting full stereo output from 2 speakers... ('http://www.datasheetcatalog.org/datasheet/philips/TDA1518BQ.pdf') I can get output when I hook either speaker to pin 9 - and quasi stereo when hooking both up to pin 9... I get nothing but buzzing which I hook either speaker to pin 5... I don't have anything configured at pins 2, 4 - which concerns me - but I can't make sense of the block diagram - and how they should be connected. My input source is an ipod and I'm using a stereo jack input. I would like stereo output from the ipod - is this possible? I'm including a schematic (minus the capacitors)... I would really appreciate help in configuring this chip. |
