ELECTRICAL CHARACTERISTICS (continued)
(VDD = PVDD = VSHDN = 3.3V, VGND = VPGND = 0V, SYNC = GND (FFM), RL = 8Ω, 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 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 = 4Ω, L = 33H.
For RL = 8Ω, L = 68H. For RL = 16Ω, L = 136H.
Note 3: PSRR is specified with the amplifier inputs connected to GND through CIN.
