Note 17. In case of measuring at SPP and SPN pins.
Note 18. Load impedance is total impedance of series resistance and piezo speaker impedance at 1kHz in Figure 34. Load
Note 19. Maximum voltage is in proportion to both AVDD and external input resistance (Rin).
Note 20. The gain is in inverse proportion to external input resistance
Note 21. PLL Master Mode (MCKI=12MHz); PMADL = PMADR = PMDAC = PMLO = PMSPK = PMVCM = PMPLL
Note 22. All digital input pins are fixed to DVDD or DVSS.

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.
Vin = 0.636 x AVDD x Rin / 20kΩ (typ).
= MCKO = PMBP = PMMP = M/S bits = “1”. MPWR pin outputs 0mA.
AVDD= 10mA(typ), DVDD=5mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=10mA(typ), DVDD=4mA(typ).
