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 = 33µH.
For RL = 8Ω, L = 68µH.
Note 3: Amplifier inputs AC-coupled to PGND with CIN = 0.47µF.
Note 4: Specified at room temperature with an 8Ω resistive load in series with a 68µH inductive load connected across BTL outputs.
Mode transitions are controlled by SHDN.
