Pin Description
The PCF8591 is a single-chip, single-supply low-power 8-bit CMOS data acquisition device with four analogue inputs, one analogue output and a serial I2C-bus interface. Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of up to eight devices connected to the I2C-bus without additional hardware. Address, control and data to and from the device are transferred serially via the two-line bidirectional I2C-bus.
