Note 1: All devices are 100% production tested at T
Note 2: Speaker amplifier testing performed with a resistive load in series with an inductor to simulate an actual speaker load. For
Note 3: Measured with the amplifier input connected to GND through C
Note 4: Speaker amplifier gain is defined as A = (V
Note 5: Testing performed with 8Ω resistive load in series with 68µH inductive load connected across the BTL output. Mode transitions
Note 6: Headphone amplifier gain is defined as A = V
Note 7: Testing performed with 32Ω resistive load connected from HP_ output to GND. Mode transitions are controlled by SHDN.
