Hi, I have an audio input signal coming in from either a signal generator or a line-level audio source (MP3 player etc). It then needs to be sometimes amplified and sometimes attenuated. The output then needs to be able to drive various transducers: sometimes speakers and sometimes custom linear actuators (inductive types). I only have single supply on the PCB so I came up with the attached schematic. The output sometimes needs to be AC coupled and sometimes it needs to ride on top of a DC offset that is half of the supply voltage. That is the reason for the jumper at the output. Is that a good way to do it? Thank you :) |
