I2C-bus controlled 4

12.1 Test and application information
(1) Supply decoupling:
The high frequency decoupling capacitors (220 nF) should be connected as close as possible to the supply pins.
It is important that these capacitors are of a good quality. When several channels are shorted to the supply simultaneously,
high peak voltages can occur at the supply line due to the activation of the protections. The high frequency decoupling
capacitors should suppress these voltage peaks.
Good results have been achieved with 0805 case size capacitors (X7R material, 220 nF) connected close to each of the
supply pins.
(2) The ACGND capacitor value must be close to four times the input capacitor value.
(3) A capacitor of 10 nF may be added from every amplier output to ground for EMC reasons.
