3D Stereo Enhancement
AK4368 features a 3D stereo enhancement function. 3D1-0 bits control the power management of the 3D function block
(Table 25), and DP1-0 bits set the 3D depth (Table 26). 3D1-0 and MUTEN bits should not be changed to avoid pop noise
for 50ms after 3D1-0 bits are changed.
4.7nF
±
20% and 470nF
±
20% capacitors should be connected at 3DCAP1, 3DCAP2 and 3DCAP3 pins as shown in Figure
25. The load capacitance at 3DCAP1, 3DCAP2 and 3DCAP3 pins should be 20pF(max), respectively.
