We are glad that we were able to resolve this issue, and will now proceed to close this thread.

LM387N replacement OP AMP

The main concern is that the circuit itself should need datashret changing with the replacement. I want to do a balancing circuit for the direct outs. No license, either express or implied, by estoppel or otherwise, is granted by TI.

Most of the typical applications shown on the datasheet can be duplicated with “normal” op-amps, but DC biasing will need to be added.

Due to the holidays, responses may be delayed. Do you have another question?

LM is a penny easier because it has a bias voltage built-in, so you can set the output around half-supply. Hi, I started planning a mod on my old console and I wanted to find an IC opamp that can run on a single supply voltage This reduces bias resistor noise contribution, allows easy single supply operation with fewer components, and provides excellent PSRR.


I haven’t seen many designs using it? Go to Support forums.

The LM has a different pin-out not normally used with dual op-amps – so any board layouts would have to change. JohnRoberts on September 06, If you have a related question, please click the ” Ask a related question ” button in the top right corner.

You may have to modify your existing circuit a bit by adding a blocking cap or a few bias resistors to use a “normal” op-amp. Mentions Tags More Cancel.

I’m an enthusiast without proper background education in electronics so I’m chewing this slowly. Some unbalance at input impedance but nothing to be alarmed for your application, as input device may not be so cool.

It is made to drive one 10K volume control in the same box, not long wires, multiple loads, etc. It also has sad output power.
