DIGITAL I/O CHARACTERISTICS
(VLDOIN = VPVDD = VSHDN = 3.7V, VGND = VPGND = 0V. TA = TMIN to TMAX, unless otherwise noted. Typical values are at
TA = +25NC.) (Note 1)
I2C TIMING CHARACTERISTICS
(VLDOIN = VPVDD = VSHDN = 3.7V, VGND = VPGND = 0V. TA = TMIN to TMAX, unless otherwise noted. Typical values are at
TA = +25NC.) (Note 1)
Note 1: 100% production tested at TA = +25NC. Specifications overtemperature limits are guaranteed by design.
Note 2: Amplifier inputs are AC-coupled to GND.
Note 3: Class D amplifier testing performed with a resistive load in series with an inductor to simulate an actual speaker load.
Note 4: CB is in pF.
