Note 2: All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 3: Specified at room temperature with an 8Ω resistive load connected across BTL output for speaker amplifier. Specified at
room temperature with a 32Ω resistive load connected between HPR, HPL, and GND for headphone amplifier. Speaker and
headphone mode transitions are controlled by SPKR_EN and HP_EN control pins, respectively.
Note 4: Amplifier inputs AC-coupled to GND.
Note 5: Maximum value is due to test limitations.
Note 6: VLDO_OUT = VLDO_OUTNOMINAL - 2%.
ELECTRICAL CHARACTERISTICS (continued)
(VDD = PVDD = CPVDD = HPVDD = HP_EN = VLDO_EN (MAX9789 only) = +5V, VGND = VPGND = VCPGND = SPKR_EN = VLDO_SET
(MAX9789 only) = 0V, ILDO_OUT (MAX9789 only) = 0, C1 = C2 = CBIAS = 1F. RL = ∞, unless otherwise specified, VGAIN1 = 0,
VGAIN2 = 5V (AVSP = 10dB, AVHP = 3.5dB), TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 2)
