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 = 8, L = 68H.
For RL = 16, L = 136H.
Note 3: PSRR is specified with the amplifier inputs connected to GND through CIN.
