High-Efficiency, Low-Noise Audio Subsystem
I2C TIMING CHARACTERISTICS
(VDD = 1.8V, VPVDD = 4.2V, 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 over temperature 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.
