Op amp U3 is configured as a current driver for the opto input, generating a current proportional to the voltage input. The opto is operated Class A with about 1 mA DC bias current. Op amp U5 is a buffer/non-inverting amplifier that amplifies the voltage across R2 to convert the opto isolator output current back to a voltage.

audio opto isolator Hi, We have two channel audio to be seperated from the final stage audio amplifier. Now becase of different products the final power ampifier keeps on changing and we come across gounding loop/ humming noise. I know that optocoupler could be used to eliminate this. Does any...

Application Notes—Analog Optical Isolators Limiters If the magnitude of an AC signal varies over a wide range, it may be necessary to amplify or compress the signal before any audio processing can be performed. In other cases, the audio power has to be limited to prevent damage to an output device. Circuits that perform

The OP stated it was for a Ham radio so it likely doesn't need to go over 5kHz for voice. But an opto with a phototransistor should be fine even for music audio if it is configured in a follower configuration, since the Miller capacitance that reduces the frequency response in a common-emitter configuration doesn't come into play.

The audio output signal appears across RV1 and is DC-decoupled via C2. TRIAC INTERFACING An ideal application for the optocoupler is that of interfacing the output of a low-voltage control circuit (possible with one side of its power supply grounded) to the input of a triac power-control circuit that is driven from the AC power lines and which ...
