Re: LM7805 Replacement #qcx #parts


 

The TLC272 is not a rail-to-rail capable op amp and can only supply
10mA. So it's not a full replacement for the TS922, though it may
suffice in this application. The TLV272 is rail-to-rail but can only
supply 7mA; it may also work. Both are inadequate for the final stage
because of the limited current capability.

I think TLC272 should also do the job, except perhaps for the final
headphone stage. It's a similarly specced part, and is available in DIP.

Regarding the supply voltage, look at the lowermost right corner. There you
see (ok, it's an educated guess) all of opamps being supplied straight from
12V rail. Common sense tells that too, since the common mode voltage used in
the circuit is 5V.
