Spesifikasi :
PCF8591 is a monolithic integrated, separate power supply, low power consumption, 8-bit CMOS data acquisition device. PCF8591 has 4 analog inputs, 1 analog output and 1 serial I2C bus interface. The 3 address pins A0, A1 and A2 of PCF8591 can be used for hardware address programming, allowing 8 PCF8591 devices to be connected to the same I2C bus without additional hardware. The address, control and data signals input and output on the PCF8591 device are all transmitted in a serial manner through the two-wire bidirectional I2C bus.
