Note 9. Input voltage is proportional to AVDD voltage. Vin = 0.107 x AVDD (typ)@MGAIN1-0 bits = “01” (+15dB),
Note 10. 83dB(typ)@MGAIN=0dB, 72dB(typ)@MGAIN=+30dB, 66dB (typ) @MGAIN=+36dB
Note 11. 89dB(typ)@MGAIN=0dB, 77dB(typ)@MGAIN=+30dB, 70dB (typ) @MGAIN=+36dB
Note 12. 100dB(typ)@MGAIN=0dB, 80dB(typ)@MGAIN=+30dB, 80dB(typ) @MGAIN=+36dB
Note 13. EXT Slave Mode (MCKI=11.2896MHz), PMADAL = PMADAR = PMADBL = PMADBR = PMVCM =
Note 14. All digital input pins are fixed to DVDD or VSS2.
(Ta=25°C; AVDD=2.4 ∼ 3.6V; DVDD=1.6 ∼ 3.6V; fs=44.1kHz)
Note 15. The passband and stopband frequencies scale with fs (system sampling rate).
Note 16. The calculated delay time caused by digital filtering. This time is from the input of analog signal to setting of the

Vin = 0.6 x AVDD (typ)@MGAIN1-0 bits = “00” (0dB).
For example, PB=20kHz= 0.454*fs (@−1.0dB). Each response refers to that of 1kHz.
PMMPA = PMMPB bits = “1” and PMPLL = M/S = MCKO bit = “0”. MPWRA/B pins outputs 0mA.
PLL Master Mode (PMPLL = M/S = MCKO bits = “1”): AVDD= 11.0 mA(typ), DVDD= 3.5 mA(typ).
16-bit data of both channels from the input register to the output register of the ADC. This time includes the
group delay of the HPF.
