AD / DA converter module for microcontrollers
using chip PFC859

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 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.
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 I2C-bus.

Single power supply
Operating supply voltage 2.5 V to 6.0 V
Low standby current
Serial input and output via I2C-bus
I2C address selection by 3 hardware address pins
Max sampling rate given by I2C-bus speed
4 analog inputs configurable as single ended or differential inputs
Auto-incremented channel selection
Analog voltage range from VSS to VDD
On-chip track and hold circuit
8-bit successive approximation A/D conversion
Multiplying DAC with one analog output.
