Note 8. It is a differential value of plus and minus input pin. Each input pins should be connected to the AC coupling
capacitance serially. The differential input is not permission when MGAIN2-0 bits are “000”. The Maximum
input voltage of MICP and MICN pins are proportional to AVDD voltage. Vin= |(MICP) − (MICN)| = 0.069 x
AVDD (max)@MGAIN2-0 bits = “001”,
0.035 x AVDD (max)@MGAIN2-0 bits = “010”, 0.017 x AVDD (max)@MGAIN2-0 bits = “011”,
0.346 x AVDD (max)@MGAIN2-0 bits = “100”, 0.218 x AVDD (max)@MGAIN2-0 bits = “101”,
0.138 x AVDD (max)@MGAIN2-0 bits = “110”, 0.098 x AVDD (max)@MGAIN2-0 bits = “111”,
ADC function is not assumed for using the exceeded input voltage.
Note 9. Output Voltage is proportional to AVDD voltage. Vout = 0.8 x AVDD (typ).
Note 10. Input Voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD (typ).
Note 11. When a PLL reference clock is FCK pin in PLL Slave Mode, S/(N+D):MICÆADC is 75dB (typ) and
S/(N+D):DACÆAOUT is 75dB(typ).
Note 12. Output Voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 13. In case of measuring between SPP pin and SPN pin directly.
Note 14. Load impedance is total impedance of series resistance and piezo speaker impedance at 1kHz in Figure 41. Load
capacitance is capacitance of piezo speaker. When piezo speaker is used, 10Ω or more series resistors should be
connected at both SPP and SPN pins, respectively.
Note 15. The maximum input voltage of the BEEP is proportional to AVDD voltage and external input resistance (Rin).
Vout = 0.6 x AVDD x Rin/20kΩ(max).
Note 16. Output Voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 17. In case of PLL Master Mode (MCKI=12.288MHz) and PMMP = PMADC = PMDAC = PMPFIL = PMSPK =
PMVCM = PMPLL = MCKO = PMAO = PMBP = PMMP = M/S =“1”. In this case, the output current of MPI
pin is 0mA.
When the AK4633 is EXT mode (PMPLL = MCKO = M/S = “0”), “AVDD+DVDD” is typically 6mA@fs=8kHz,
9mA@fs=48kHz.
Note 18. All digital inputs pins are fixed to DVDD or DVSS.
