Audio signals meant to go between equipment but not directly from microphones or meant to drive a speaker are usually at line level, which is usually around 1 V RMS. That is about the right amplitude for driving a microcontroller A/D input, but the DC level needs to be set close to half of the A/D range. This is what R2 and R3 do in this circuit.

14. 0. Jul 27, 2012. HI All. I am building a audio interface for my microcontroller, PSoC5. Problem is audio is transmitted through mini jacks in the range -2V to +2V and my PSoC5's ADC can only measure 0-5V. So I have to raise the -2 to +2V to my ADC range, but how? further more I assume that some kind of AC coupling is nessesary?

The interfacing circuits can also be used with any PIC microcontrollers such as the PIC16F84, although these microcontrollers may require programming in assembler code. This section is split into four subsections: • Introduction to ‘standard’ interfacing circuits • Output Device Interfacing • Input Device Interfacing
