AFE4300: Can We Leave Unused IOUT and VSENSE Pins Open?

Wayne Chen (Audio AE)

Part Number: AFE4300

Hi Sirs,

As title, can we leave VSENSE and IOUT pins open when not used? If not, do we have termination circuit for customers?

Thank you and Best regards,

Hi Wayne,

The unused IOUT pins can be connected to GND.
The unused VSENSE pins can be left floating.
In any case, they are disconnected from the AFE4300 signal chain because of the open switches (ISW_MATRIX and VSW_MATRIX).
