Notes ;
Input signal frequency is 1KHz.
(1) Peak to peak value. Applies to MICIN terminal
(2) Any voltage can be used if input resistor attached externally to MICIN is selected properly
VIA=R/9.4K, When value of a resistor was shown with R,
(3) Peak to peak value. Applies to AOL and AOR terminals. The output voltage is in proportion to AVDD.
(4) Uses IHF-A
(5) The signal is outputted through MICIN inputs to digital outputs via Volume.
(6) Input resistor attached externally to MICIN : 47 k
W. 0 dB = 4.65 Vpp
(7) The signal is outputted through MICIN inputs to AOL and AOR via volume.
