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 or VSS. PWADN and PWDAN pins are held to VSS. |
