De-emphasis Filter
The AK4626A includes the digital de-emphasis filter (tc=50/15μs) by IIR filter. De-emphasis filter is not available in
Double Speed Mode and Quad Speed Mode. This filter corresponds to three sampling frequencies (32kHz, 44.1kHz,
48kHz). De-emphasis of each DAC can be set individually by register data of DEMA1-C0 (DAC1: DEMA1-0, DAC2:
DEMB1-0, DAC3: DEMC1-0, see “Register Definitions”).

Digital High Pass Filter
The ADC has a digital high pass filter for DC offset cancel. The cut-off frequency of the HPF is 1.0Hz at fs=48kHz and
scales with sampling rate (fs).
