Note 7. The voltage difference between MICP and MICN pins. AC coupling capacitor should be inserted in series at each
input pin. Full-differential microphone input is not available at MGAIN3-0 bits = “1000” or “0000”. If the input
signal over those maximum voltages are input, the ADC does not operate properly.
Note 8. When a PLL reference clock is input to the FCK pin in PLL Slave Mode, S/ (N+D) of MICÆADC is 75dB (typ),
S/ (N+D) of DACÆAOUT is75dB (typ).
Note 9. When LOVL bit = “1”, large-amplitude output may have clip noise.
Note 10. When SPGK1-0 bits = “01” or “10”, large-amplitude output may have clip noise if the SVDD is low.
Note 11. The maximum input voltage is inversely proportional to the external input resistance (Rin). Vout = Vin ×
Rin/33kΩ(max). The volume can not be changed by BPLVL 7-0 bits in “BEEP pin External Input Resistance
Mode” (BPM1-0 bits = “10”). BPLVL 7-0 bits should be fixed “00H” to change the gain by the external
resistance (Rin).
Note 12. Input Voltage does not depend on VVDD voltage.
Note 13. Measurement point is A of Figure 2.
Note 14. This is the value when the lowest input signal level is more than -20IRE.
Note 15. When PLL Master Mode (MCKI=12MHz), and PMV = PMMP = PMADC = PMDAC = PMPFIL = PMSPK =
PMVCM = PMPLL = MCKO = PMAO = M/S = “1”. The MPI pin outputs 0mA. In EXT mode, when PMPLL=
MCKO= M/S= “0” and LP= “0”, AVDD+ DVDD= 6mA (fs=8kHz, typ) or 9mA (fs=48kHz, typ), when LP=
“1”, AVDD+DVDD = 5mA (fs=8kHz, typ).
Note 16. When Black signal is input to the VIN pin, and the VOUT pin has no load resistance. If the resistance is 150Ω,
it is 12.5mA(typ).
Note 17. Set LP bit = “1” when sampling frequency ≤ 22.05kHz, set LP bit = “0” when > 22.05kHz.
Note 18. All digital input pins are fixed to DVDD or VSS2.
