Hi, I have just a basic question about best practices. I am generating a voltage and buffering it through an opamp. I then want to split the signal to control two separate sub circuits (In both cases the signal simply biases another op-amp to control some aspect of the sub-circuit). When I split the signal, should I run each line through a simple transistor buffer or something so that the two circuits are isolated, or would it be unnecessary.
I have the thing breadboarded and it seems to work with both setups. But I am just wondering if adding the buffer is better design.
