Product Description

Introduction
About PCF8591 AD/DA Chip
The PCF8591 is a single-chip， single-supply and low-power 8-bit CMOS data acquisition device with four analog inputs， one analog 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.
