n
De-emphasis filter
The AK4360 includes the digital de-emphasis filter (tc=50/15
μ
s) by IIR filter. This filter corresponds to 44.1kHz
sampling. Setting DEM pin “H” enables the de-emphasis.
n
Low Frequency Boost Function
When BOOST pin goes “H”, high pass filter characteristics which is made by a external capacitor (220
μ
F) and a resistor
(16
) can be corrected. The cut-off frequency is 45Hz@fs=44.1kHz.
