MAX98302
Stereo 2.4W Class D Amplifier
ELECTRICAL CHARACTERISTICS (continued)
(VPVDD = VSHDN = 5.0V, VPGND = 0V, AV = 12dB (GAIN = PVDD), RL = J, RL connected between OUT_+ to OUT_-, 20Hz to 22kHz
AC measurement bandwidth, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25NC.) (Notes 2, 3)
Note 2: All devices are 100% production tested at TA = +25NC. All temperature limits are guaranteed by design.
Note 3: 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 4: Amplifier inputs AC-coupled to ground.
Note 5: Mode transitions controlled by SHDN.
