De-emphasis Filter
A digital de-emphasis filter is built-in (tc = 50/15µs). DEM pin is internal pull-down pin. Setting DEM pin “H” enables
the digital de-emphasis filter. Refer to the section of “FILTER CHARACTERISTICS” regarding the gain error when the
de-emphasis filter is enabled. De-emphasis filter is off when double/quad speed mode.
