4. External Analog Outputs Circuit
The output level of this circuit is 2.83Vpp (AK4436: typ. 2.83Vpp). Normally, DC component is cut by an
external capacitor since the DAC outputs have DC offsets of a few millivolts to the VCOM voltage. The
cutoff frequency of HPF is shown below.
fc= 1/(2 × π × R × C) [Hz]
Where the C is the external AC coupling capacitor and the R is load resistance.
When C = 1μF and R = 10kΩ, then fs = 16Hz.
