A first look on the 4 channel volume control
This 4 channel volume control is based on the Burr-Brown PGA 4311. The input is buffered by a quad opamp. The module needs a +/-5V power supply. Digital input is fully isolated by optocouplers.
The circuit can be controlled from any microcontroller. Examples for Arduino and Raspberry Pi are available.
The module size is 5x5cm, expect more modules in this size in the future.
