LED output during Record operation.
VCCA, VCCD and VCCP are connected together. VSSA, VSSP1, VSSP2 and VSSD are connected together.
REC , PLAY , FT , FWD , ERASE , VOL and RESET must be at VCCD.
Balanced input signal applied between MIC+ and MIC- as shown in the applications example. Single-ended MIC+ or
MIC- input is recommended to be less than 100 mV p-p.
