PCF8591 Module Analog to Digital / Digital-Analog Converter Module

PCF8591 Module Analog to Digital / Digital-Analog Converter Module

This is a breakout/prototype board designed for the PCF8591 IC. The PCF8591 is a low-power, 8-bit CMOS data acquisition device that operates on a single supply. It features four analog inputs, one analog output, and a serial I²C-bus interface for easy communication.

The module includes three address pins—A0, A1, and A2—which allow you to set the hardware address, enabling the connection of up to eight devices on the same I²C bus without the need for additional hardware. Data transfer to and from the device is done serially via the bidirectional I²C bus.

The PCF8591 offers key features such as analog input multiplexing, an on-chip track-and-hold function, 8-bit analog-to-digital conversion, and 8-bit digital-to-analog conversion. The maximum conversion rate is determined by the speed of the I²C bus.
