Note 8. The passband and stopband frequencies scale with fs (system sampling rate).
Note 9. This value is the time from the rising edge of LRCK after data is input to rising edge of LRCK after data is
output, when LRCK for Output data corresponds with LRCK for Input.(at 20bit MSB justified, 16bit and 20bit
LSB justified)

Normal operation: (PDN = “H”, Path Mode 0)
FSI=FSO=48kHz at Slave Mode
(I2MODE= OMODE = “L”): VDD=3.3V
FSI=48kHz,FSO=96kHz at Master Mode
(I2MODE=OMODE= “H”) : VDD=3.3V
: VDD=3.6V
Power down: PDN = “L”
