(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 TAS5112A. It is recommended
to follow the TAS5112F2EVM (S/N 112) design and layout guidelines for best performance.
