ELECTRICAL CHARACTERISTICS (continued)
(VPVDD = VSHDN = 5V, VPGND = 0V, RL = ∞, unless otherwise specified. RL connected between OUT+ and OUT-, AC measurement
bandwidth 20Hz to 22kHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 2)
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 = 4, L = 33H.
For RL = 8, L = 68H.
Note 3: Amplifier inputs AC-coupled to PGND with CIN = 0.47F.
Note 4: Specified at room temperature with an 8
resistive load in series with a 68H inductive load connected across BTL outputs.
Mode transitions are controlled by SHDN.
