8-bit A/D and D/A converter  
Rev. 7 — 27 June 2013  
Product data sheet  
1. General description  
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.  
2. Features and benefits  
Single power supply  
Operating supply voltage 2.5 V to 6.0 V  
Low standby current  
Serial input and output via I2C-bus
