Note 2. The offset of ADC is removed by internal HPF.
Note 3. Input/Output of ADC and DAC scales with VDD voltage. 0.6 x VDD(typ).
Note 4. PSR is applied to VDD with 1kHz, 50mV. No signal is input to AINL/R pins and “0” data is input to SDTI pin.
Note 5. In case of power-down mode, all digital input including clocks pins (MCLK, SCLK and LRCK) are held to VDD
