CSD95373AQ5M: About VDD pin

Part Number: CSD95373AQ5M


Customer wants to install a 2.2kΩ resistor on VDD.
In the background, the customer is trying to check the rated power of the resistor.
Could you tell me the maximum value of VDD operating supply current?


  • Hi Yusuke,

    Thank you for your interest in the CSD95373A. 

    VDD bias current is a strong function of switching frequency.  Please refer to Figure 10 in the datasheet for information on typical operating supply current versus switching frequency.  In order to size the power supply for VDD, I would recommend adding 30% margin to the value determined from the graph based on your use case.
