AK4682 Datasheet, PDF (26/43 Pages) Asahi Kasei Microsystems – Multi-channel CODEC with 2Vrms Stereo Selector

[AK4682]
■ Input Selector, Input Attenuator
The AK4682 includes 8:4 stereo input/output selectors. The AIN2-0, AOUT12-10, AOUT22-20, AOUT32-30 bits set
each input channel (Table 22, Table 23, Table 24, Table 25). To select the DAC1 or DAC2, set PWAD bit = PWDA bit
= PWANA bit = “1”.
