This is for an audio amplifier. An audio signal has to go in an Automatic Gain control whose supply voltage is from 0 to 5 V. After that I will generate a PWM signal by a ST7, an this signal will be rebuilt by a class D amplifier.
But I have a problem with the Automatic gain control.
Thank you for your explanations.
