RECOMMENDED OPERATING CONDITIONS
(AVSS, DVSS, HVSS=0V; Note 3)
Parameter
Power Supplies
(Note 10) Digital
Note 3. All voltages with respect to ground.
Note 10. The power-up sequence between AVDD, DVDD and HVDD is not critical. When only AVDD or HVDD is
powered OFF, the power supply current of DVDD at power-down mode may be increased. DVDD should not be
powered OFF while AVDD or HVDD is powered ON.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
ANALOG CHARACTERISTICS
(Ta=25
°
C; AVDD, DVDD, HVDD=3.3V; AVSS=DVSS=HVSS=0V; fs=44.1kHz, BICK=64fs;
Signal Frequency=1kHz; 16bit Data; Measurement frequency=20Hz
20kHz; unless otherwise specified)
Parameter
MIC Amplifier:
LIN1/RIN1/LIN2/RIN2 pins & LIN3/RIN3 pins (AIN3 bit = “1”);
MDIF1=MDIF2 bits = “0” (Single-ended inputs)
MGAIN1-0 bits = “00”
Input
Resistance
MGAIN1-0 bits = “01”, “10”or “11”
MGAIN1-0 bits = “00”
MGAIN1-0 bits = “01”
MGAIN1-0 bits = “10”
MGAIN1-0 bits = “11”
MIC Amplifier:
IN1+/IN1
/IN2+/IN2
pins; MDIF1 = MDIF2 bits = “1” (Full-differential input)
Maximum Input Voltage (Note 11)
MGAIN1-0 bits = “01”
MGAIN1-0 bits = “10”
MGAIN1-0 bits = “11”
MIC Power Supply:
MPWR pin
Output Voltage (Note 12)
Load Resistance
Load Capacitance
Note 11. The voltage difference between IN1/2+ and IN1/2
pins. AC coupling capacitor should be inserted in series at
each input pin. Full-differential mic input is not available at MGAIN1-0 bits = “00”. Maximum input voltage of
IN1+, IN1
, IN2+ and IN2
pins is proportional to AVDD voltage, respectively.
Vin = 0.069 x AVDD (max)@MGAIN1-0 bits = “01”, 0.035 x AVDD (max)@MGAIN1-0 bits = “10”, 0.017 x
AVDD (max)@MGAIN1-0 bits = “11”.
When the signal larger than above value is input to IN1+, IN1
, IN2+ or IN2
pin, ADC does not operate
normally.
Note 12. Output voltage is proportional to AVDD voltage. Vout = 0.75 x AVDD (typ)
