ELECTRICAL CHARACTERISTICS (continued)
(VPVDD = VSHDN = 5.0V, VPGND = 0V, AV = 12dB (GAIN = PVDD), RL = J, RL connected between OUT+ to OUT-, AC measurement
bandwidth 20Hz to 22kHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25NC.) (Notes 1, 2)
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.
