I2C TIMING CHARACTERISTICS
(VDD = PVDD = CPVDD = SHDN = 3.3V, GND = PGND = CPGND = 0V, SYNC = VDD (SSM), speaker gain = +12dB, headphone gain
= +1dB. Speaker load RL connected between OUT+ and OUT-, unless otherwise noted. RL =
∞. Headphone load RLH connected
between HPR/HPL and GND. CBIAS = 1F to GND, 1F capacitor between C1P and C1N, CVSS = 1F. TA = TMIN to TMAX, unless
otherwise noted. Typical values are at TA = +25oC.) (Figure 9)

Note 1: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 2: Speaker mode testing performed with a resistive load in series with an inductor to simulate an actual speaker load. For RL =
4
, L = 34H, RL = 8, L = 68H.
Note 3: Amplifier inputs (STEREO/MONO) connected to GND through CIN.
Note 4: Speaker mode testing performed with an 8
resistive load in series with a 68H inductive load connected across BTL out-
put. Headphone mode testing performed with 32
resistive load connected to GND. Mode transitions are controlled by
SHDN. KCP level is calculated as: 20 x log[(peak voltage under normal operation at rated power level)/(peak voltage during
mode transition, no input signal)]. Units are expressed in dB.
Note 5: Cb = total capacitance of one bus line in pF.
