TDA7293 - Need help on circuit
Hi All!
I found the following circuit at http://home.s-planet.de/t.dauner/7293/ It is quite similar to the one which was published in UB electronics some time back. Can someone explain the function of the caps/resistor network between Pin 2 & 14. The recommended circuit has only 1 resistor between those pins. Thanks! |

100u caps are there to set DC gain to 1
R103 - feedback resistor C3 prevents oscillation C1 bypasses 100u caps R1 - don't know for sure R102 - gain setting resistor
