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
capacitance is capacitance of piezo speaker. When piezo speaker is used, 10
Ω
or more series resistors should be
connected at both SPP and SPN pins, respectively.
Note 19. Maximum voltage is in proportion to both AVDD and external input resistance (Rin).
Vin = 0.636 x AVDD x Rin / 20k
Ω
(typ).
Note 20. The gain is in inverse proportion to external input resistance

): AVDD=10mA(typ), DVDD=4mA(typ).
Note 22. All digital input pins are fixed to DVDD or DVSS.
