PCF8591-ADC-DAC Analog Digital Converter Module

The PCF8591 is a 8-bit CMOS data acquisition device. The PCF8591 has the four analog inputs, one analog output and a serial I2C bus interface. PCF8591 has three address pins A0, A1 and A2 that can be used to set the I2C hardware address, 8 PCF8591 could be on the same I2C bus, without the need for additional hardware. On the PCF8591 control and data signals are transmitted in serial fashion via the two-wire bidirectional I2C bus.
