Has anyone played with the Radio Shack audio amplifier IC? I don't remember the model # or catalog #, but it's a 8-pin IC. I have a few of them that I got god knows where (some surplus stuff), and they come with the pin-outs, but no specifications. There are 2 pins labled Gain. I supposed I have to connect them via a resistor or something to adjust the amplifier gain, but I don't know what I need. I've had the amplifier working, but they seem to overdrive themselves and eventually burn out. Does anybody have any information on them? --- Jeff +----------------------------------------------+------------------------------+ | Jeff DePolo [depolo@eniac.seas.upenn.edu] | o The best things in life | | => The University of Pennsylvania <= | come in six-packs. | | Class of 1991 - Computer Science Engineering | o Life begins at 85 MPH. | +----------------------------------------------+ o It's not illegal if they | | DISCLAIMER: Someone else used my account. | don't catch you. | +----------------------------------------------+------------------------------+
