ELECTRICAL CHARACTERISTICS (VDD = 3.3V)
(VDD = PVDD = SHDN = MUTE = 3.3V, GND = PGND = 0V, SYNC = GND (FFM). Gain = 12dB (G1 = 0, G2 = 1). Speaker load resis-
tor (RL) connected between OUT+ and OUT-, unless otherwise noted. RL =
∞, 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.
Note 3: Inputs AC-coupled to GND.
Note 4: Testing performed with 8
resistive load in series with a 68H inductive load across BTL outputs. Mode transitions are con-
trolled by the SHDN pin.
