Fig. 5.3.4 Audio Isolator Using Phototransistor Mode Method 1. Basic Audio Optocoupler. The circuit shown in Fig. 5.3.4, adapted from a design in Newnes Electronic Circuits Pocket Book by Ray Marston (ISBN 10:1-4832-9192-8) uses the 4N25 connected as a phototransistor to pass audio signals whilst isolating the input and output circuits.

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.

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
