huangyong 0 Report post Posted July 30, 2004 However, I've learnt something new recently it regards to opamps & it sounds interesting enough. Called a "discrete Opamp" ... I think it works only for dual ones like the OPA2604, LM6172 etc. Take two of the same opamps & flatten out their legs. For one opamp snip off pins 7,6 & 5 for the other, snip off pins 1, 2 & 3. Now you have a set of two opamps that will now be combined to make one opamp. Assuming the socket starts with pin 1 on the extreme upper left ... slot the opamp with pins 1,2,3 & 4 into the left of the socket & the opamp with pins 5, 6, 7 & 8 into the right side of the socket. Bridge (ie. attach) the 2 remaining pins 4 & 8 (from each opamp) together. Each opamp is now running one side each. Dual opamps have a left & right channel ... by using two opamps in the method above ... both sides are (literally) separated (ie. discrete). Suppose to have less distortion & noise cos both channels have no chance of interacting with one another. what is that?? can anyone confirm with me it really works. found in an old thread in echoloft. echoloft Share this post Link to post Share on other sites
