ELECTRICAL CHARACTERISTICS (continued)
(PV
mode), SHDN = MUTE = high, G1 = low, G2 = high (A
connected between OUT_+ and OUT_-, unless otherwise stated. T
= +25°C.) (Note 1)
Note 1: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 2: Inputs AC-coupled to GND.
Note 3: Testing performed with an 8Ω resistive load in series with a 68µH inductive load across the BTL outputs.
Note 4: Minimum output power is guaranteed by pulse testing.
Note 5: Testing performed with an 8Ω resistive load in series with a 68µH inductive load connected across BTL outputs. Mode tran-
Note 6: Testing performed with a 4Ω resistive load in series with a 33µH inductive load across the BTL outputs.
