(1) To optimize device performance and prevent overcurrent (OC) protection tripping, the demodulation filter must be designed with special care. See
Demodulation Filter Design in the Application Information section of the data sheet and consider the recommended inductors and capacitors for
optimal performance. It is also important to consider PCB design and layout for optimum performance of the TAS5111. It is recommended to follow
the TAS5026-5111KEVM (S/N 001) design and layout guidelines for best performance.
