7 / 32 page 1.8W, Filterless, Stereo, Class D Audio Power Amplifier and DirectDrive Stereo Headphone Amplifier _______________________________________________________________________________________ 7 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 = 1µF to GND, 1µF capacitor between C1P and C1N, CVSS = 1µF. TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25oC.)

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 = 4Ω, L = 34µH, RL = 8Ω, L = 68µH. Note 3: Amplifier inputs (STEREO/MONO) connected to GND through CIN. Note 4: Speaker mode testing performed with an 8Ω resistive load in series with a 68µH inductive load connected across BTL out- put. Headphone mode testing performed with 32Ω 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. |
