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 R = 4 , L = 33µH.

For R = 8 , L = 68µH.

Note 3: Inputs AC-coupled to GND.

Note 4: Testing performed with 8 resistive load in series with a 68µH inductive load across BTL outputs. Mode transitions are con-

trolled by the SHDN pin.
