Datasheet TDA51S-41HC (Mornsun) - 9

Figure11. Isolated Power and SPI for ADC Sensing Application with TDA51S-41HC Design requirement: Parameter Value Input voltage VIN 3.0V to 5.5V Decoupling capacitors between VCC and GND1 0.1uF, 22uF Decoupling capacitors between VISO and GND2 0.1uF, 47uF Because of the higher current flowing though the VCC and VISO power supplies of TDA51S-41HC, higher decoupling capacitors usual y provide better noise and ripple performance. Although a 10uF capacitor is enough to ensure the normal operation of the product, it is stil strongly recommended to use a higher decoupling capacitor( such as 22uF, 47uF) on both VCC and VISO pins to the respective grounds to achieve the best performance.
