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.
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.
Vout = 0.6 x AVDD x Rin/20kΩ(max).
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.
