Hi All,
I finished populating a CMOY using the Tangent layout today. When I completed the power stage, I tested it, and it V+ to ground was +4.6v, V- to ground -4.6v. After I finished putting in the amplification stage, I soldered a few resistor leads on to clip alligators to for testing, and... nothing. I starting checking connections for resistance, couldn't find any bad joints or solder bridges.
I discovered that with the OpAmp plugged in, I'm getting 7.5v @ V+ to ground, and -1.6v @ V- to ground. What gives? Take the opamp out of the socket, and all is well again.
Pics will be forthcoming tomorrow if they're needed.
All assistance greatly appreciated!
