Note 1: All devices are 100% production tested at +25NC. 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 = 4I,

L = 33FH. For RL = 8I, L = 68FH.

Note 3: Amplifier inputs AC-coupled to ground.

Note 4: Mode transitions controlled by SHDN.
