PCF8591 Module Analog to Digital / Digital-Analog Converter Module

This is a breakout board/Prototype Board for PCF8591 IC. The PCF8591 is a single-chip, single?supply low?power 8?bit CMOS data acquisition device with four analog inputs, one analog output, and a serial I?C?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 I?C?bus without additional hardware. Address, control, and data to and from the device are transferred serially via the two-line bidirectional I?C?bus.

The functions of the device include analog input multiplexing, on-chip track and hold function, 8-bit analog?to?digital conversion, and an 8?bit digital?to?analog conversion. The maximum conversion rate is given by the maximum speed of the I?C-bus.
