Note 14. The full scale of Input signal of MIN pin is 1.98Vpp.
Note 15. In case of measuring between SPP pin and SPN pin directly.
Note 16. There are no relations with the setup of SPKG1-0 bits, and it is the same value.
Note 17. Load impedance is total impedance of series resistance and piezo speaker impedance at 1kHz in Figure 35. Load
Note 18. The maximum input voltage of the BEEP is proportional to AVDD voltage and external input resistance(Rin).
Note 19. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.66 x AVDD (max)
Note 20. When ALC2 Gain is changed, this typical value changes between 22kΩ and 26kΩ.
Note 21. Output Voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ)
MS0396-E-00
(Note 14)
BEEP
BEEP
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.
Vout = 0.6 x AVDD x Rin/20kΩ(max).
