ELECTRICAL CHARACTERISTICS (continued)
(VDD = PVDD = CPVDD = 3.3V, GND = PGND = CPGND = 0V, SHDN = VDD, I2C settings (INA gain = +20dB, INB gain = INC gain =
0dB, volume setting = 0dB, mono path gain = 0dB, SHDN = 1, SSM = 1). Speaker load resistors (RLSP) are terminated between
OUT+ and OUT-, headphone load resistors are terminated to GND, unless otherwise noted. C1 = C2 = C3 = 1F. TA = TMIN to TMAX,
unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 2: Measured at headphone outputs.
Note 3: Amplifier inputs AC-coupled to GND.
Note 4: Testing performed with a resistive load in series with an inductor to simulate an actual speaker load. For RL = 8Ω L = 68H,
RL = 4Ω L = 47H.
Note 5: Testing performed at room temperature with an 8Ω resistive load in series with 68H inductive load connected across BTL
outputs for speaker amplifier. Testing performed with 32Ω resistive load connected between OUT_ and GND for headphone
amplifier. Testing performed with a 32Ω resistive load connected between OUTRx and GND for mono receiver amplifier.
Mode transitions are controlled by SHDN pin.
