Test Pins (Input) - These pins are unused inputs. It is recommended that these pins be tied to a supply

(VL or GND) to minimize leakage current. The CS8406 will operate correctly if these pins are left float-

ing, however current consumption from VL will increase by 25

μA per TEST pin that is left floating.

Thermal Pad

-

Thermal Pad (QFN package only) - Thermal relief pad for optimized heat dissipation. This pad must be

electrically connected to GND. See“Power Supply, Grounding, and PCB layout” on page 33 for more

information.
