Note 2: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 3: PSRR is specified with the amplifier inputs connected to GND through CIN.
Note 4: Testing performed with a resistive load in series with an inductor to simulate an actual speaker load. For RL = 8
, L = 68H.
For RL = 12
, L = 100H. For RL = 16, L = 120H.
Note 5: Output power measured at TA = +25°C, with a soak time of 15 minutes.
