Part Number: HD3SS3212

Hi David Liu,

Customer is considering this deivce to reduce their board size using the switching configuration of DP 2-Lain and I2C/GPIO. Please check the file below and let me know if there are any issues. Also, please let me know if there is the internal coupling capacitor each signal line.

Hello Jeffrey,

Your schematic looks fine and should operate without any issues. You have 0.1uF capacitors on A0+/- pins, AC coupling caps on VCC, and a pull-down resistor on the enable pin.

Best,

Caroline

Hi Caroline,

Thank you for your feedback. I used the diagram of typical application in the datasheet to explain the customer's configuration, so other components you comment are remain on the diagram. One more thing, please let me know if there is the internal coupling capacitor each signal line.

Hello Jeffrey,

There are capacitors inside the device but there are no coupling capacitors. Those need to be externally added.

Best,

Caroline
