Note 21. Output voltage is proportional to AVDD voltage.
Vout = 0.94 x AVDD(typ)@SPKG1-0 bits = “00”, 1.19 x AVDD(typ)@SPKG1-0 bits = “01”, 2.05 x
AVDD(typ)@SPKG1-0 bits = “10”, 2.58 x AVDD(typ)@SPKG1-0 bits = “11” at Full-differential output.
Note 22. In case of measuring at SPP and SPN pins.
Note 23. Load impedance is total impedance of series resistance (R
series
) and piezo speaker impedance at 1kHz in Figure
61. Load capacitance is capacitance of piezo speaker. When piezo speaker is used, 10
or more series resistors
should be connected at both SPP and SPN pins, respectively.
Note 24. Maximum voltage is in proportion to both AVDD and external input resistance (Rin). Vin = 0.6 x AVDD x Rin
/ 20k
(typ).
Note 25. The gain is in inverse proportion to external input resistance.
