15 APPLICATION INFORMATION

In order to prevent excessive ground and supply noise and to minimize cross-talk of the digital to analog signal paths the

user has to design the printed-circuit board layout very carefully. Supply lines common to a PCF8591 device and noisy

digital circuits and ground loops should be avoided. Decoupling capacitors (>10

µF) are recommended for power supply

and reference voltage inputs.
