MAX98502
Boosted 2.2W Class D Amplifier
with Automatic Level Control
ELECTRICAL CHARACTERISTICS (continued)
(VBAT = 3.6V, RL = J between SPKP and SPKN, AV = +6dB, CIN = 1FF, 20Hz to 22kHz AC measurement bandwidth, TA = TMIN to
TMAX, unless otherwise noted. Typical values are at TA = +25NC.) (Note 2)
Note 2: 100% production tested at TA = +25NC. Specifications over temperature limits are guaranteed by design.
Note 3: Amplifier inputs are AC-coupled to AGND.
Note 4: Mode transitions are controlled by SDSPK.
