ELECTRICAL CHARACTERISTICS (continued)
(VDD = PVDD = VSHDN = 3.3V, VGND = VPGND = 0, SYNC = GND (FFM), RL = ∞, RL connected between OUT+ and OUT-,
TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 2)
Note 1: All devices are 100% production tested at +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 = 4, L = 33H.
For RL = 8, L = 68H. For RL = 16, L = 136H.
Note 3: Inputs AC-coupled to GND.
Note 4: Testing performed with 8
resistive load in series with 68H inductive load connected across BTL output. Mode transitions
are controlled by SHDN pin. KCP level is calculated as 20 x log[(peak voltage under normal operation at rated power
level)/(peak voltage during mode transition, no input signal)]. Units are expressed in dB.
Note 5: SYNC has a 1M
resistor to VREF = 1.25V.
