Working Principle of PCF8591 AD/DA Module

The PCF8591 module works by converting analog voltage signals into digital data that can be processed by a microcontroller. The analog input channels sample voltage levels and convert them into 8-bit digital values.

At the same time, the module includes a digital-to-analog converter that can generate an analog voltage output from digital data sent by the microcontroller. Communication between the controller and the module is handled via the I2C bus, requiring only two data lines.
