CHIP DATA SHEET
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
ƒÞ Operating supply voltage 2.5 V to 6.0 V

ƒÞ 4 analog inputs configurable as single ended or differential inputs
ƒÞ Auto-incremented channel selection
ƒÞ Analog voltage range from VSS to VDD
ƒÞ On-chip track and hold circuit
ƒÞ 8-bit successive approximation A/D conversion
ƒÞ Multiplying DAC with one analog output.

California Proposition 65 Warning WARNING: This product can expose you to chemicals including Nickel which is known to the State of California to cause cancer and which is known to the State of California to cause birth defects and/or other reproductive harm. For more information, go to www.P65Warnings.ca.gov
Click to see Why is this here? As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.

As an example:
   ABS plastic contains styrene
   PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
   electrolytic capacitors can contain Ethylene glycol
   Brass can contain Lead
   flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
   Aluminum alloys can contain Chromium

To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
