       High quality PCF8591 module AD / DA conversion modules analog-to-digital / digital-to-analog conversion        

 

  One PCF8591 AD / DA chip introduced

    

The PCF8591 Is a monolithically integrated, and a separate power supply, low-power, 8-bit CMOS data acquisition devices. The PCF8591 has the four analog inputs, one analog output and a serial I2C bus interface. PCF8591 three address pins A0, A1 and A2 can be used in hardware address programmed 8 PCF8591 device allows access to the same I2C bus, without the need for additional hardware. On the PCF8591 device input and output of the address, control and data signals are transmitted in serial fashion via the two-wire bidirectional I2C bus.

 

PCF8591 main performance indicators:
