I 1.8V Power Input Pin (LDOE pin = "L")
Power-Down & Reset Pin
48 PDN I When this pin is "L", the AK4458 is powered-down and the control registers are reset to default
state.
Note 2. All input pins except internal pull-up/down pins should not be left floating.
Note 3. PCM mode and DSD mode are controlled by registers. Daisy Chain mode is controlled by both
registers and pins.
Note 4. This pin outputs DVSS when the LDOE pin = "H" and Hi-z when the LDOE pin = "L".
