_______________________________________________________________________________________
Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: Testing performed with a resistive load in series with an inductor to simulate an actual speaker load. For RL = 8Ω, L = 68H.
Note 3: Device muted by either asserting MUTE or minimum VOL setting.
Note 4: Cb = total capacitance of one bus line in pF.
ELECTRICAL CHARACTERISTICS (continued)
(VPVDD = 12V, VDD = 3.3V, VGND = VPGND = 0, V SHDN = VDD, VMUTE = 0; Max volume setting; speaker load resistor connected
between OUT+ and OUT-, RL =
∞, unless otherwise noted. CBIAS = 2.2F, C1 = C2 = 0.1F, CIN = 0.47F, RIN = 20kΩ, RF = 30kΩ,
SSM mode. Filterless modulation mode (see the
Functional Diagram/Typical Application Circuit). TA = TMIN to TMAX, unless otherwise
noted. Typical values are at TA = +25°C.) (Note 1)
