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 = â1000â or â0000â. 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 MICÃADC is 75dB (typ),
S/ (N+D) of DACÃAOUT is75dB (typ).
Note 9. When LOVL bit = â1â, large-amplitude output may have clip noise.
Note 10. When SPGK1-0 bits = â01â or â10â, 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 Ã
Rin/33kΩ(max). The volume can not be changed by BPLVL 7-0 bits in âBEEP pin External Input Resistance
Modeâ (BPM1-0 bits = â10â). BPLVL 7-0 bits should be fixed â00Hâ 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 = â1â. The MPI pin outputs 0mA. In EXT mode, when PMPLL=
MCKO= M/S= â0â and LP= â0â, AVDD+ DVDD= 6mA (fs=8kHz, typ) or 9mA (fs=48kHz, typ), when LP=
â1â, 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 = â1â when sampling frequency ⤠22.05kHz, set LP bit = â0â when > 22.05kHz.
Note 18. All digital input pins are fixed to DVDD or VSS2.
