Note 2: 100% production tested at TA = +25NC. Specifications over temperature limits are guaranteed by design.
Note 3: The MAX98400A stereo mode is specified with an 8I resistive load in series with a 68FH inductive load connected across
BTL outputs. The MAX98400A mono mode is specified with a 4I resistive load in series with 33FH inductive load. The
MAX98400B is specified with an 8I resistive load in series with a 68FH inductive load connected across BTL outputs.
Note 4: Amplifier inputs AC-coupled to GND.
Note 5: Mode transitions controlled by SHDN.
Note 6: Relative to equivalent full-scale undistorted output. Full scale (FS) = VPVDD x 0.95.
Note 7: Relative to equivalent full-scale undistorted output. Full scale (FS) = VPVDD.
ELECTRICAL ChARACTERISTICS (continued)
(VPVDD = 18V, CIN = 1FF, VSHDN = 5V, LIM_TH = VS, TEMPLOCK = unconnected; G1 = GND, G2 = open (gain = 20.1dB), CREL
= 1FF, C1 = C2 = 1FF, RL = J, AC measurement bandwidth 20Hz to 20kHz, differential input signal, TA = TMIN to TMAX, unless
otherwise noted. Typical values are at TA = +25NC.) (Notes 2, 3)
