To optimize device performance and prevent overcurrent (OC) protection activation, the demodulation filter must be designed with
special care. See Demodulation Filter Design in the Application Information section of this 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
TAS5121I.
