ELECTRICAL CHARACTERISTICS (continued)
(VDD = PVDD = HPVDD = 5V, GND = PGND = CPGND = 0V, SHDN = VDD, GAIN1 = GAIN2 = GND (SPKR = +9dB, HP = 0dB), HPS =
GND, FS0 = FS1 = GND (800Hz), MGAIN = float (-6dB), SYNC_IN = VDD (SSM), speaker load RL connected between OUT_+ and
OUT_-, unless otherwise noted, RL =
∞. Headphone load RLH connected between HPR/HPL to GND, RLH = ∞. CBIAS = 1F to GND,
C1 = 1F, C2 = 1F. TA = TMIN to TMAX, unless otherwise noted. Typical values at TA = +25°C.) (Note 1)

Note 1: All devices are 100% tested at TA = +25°C. Limits over temperature are guaranteed by design.
Note 2: Measured at 2kHz for OUTL_, OUTR_, HPL, and HPR; measured at 100Hz for OUTM_.
Note 3: PSRR is measured with the inputs AC-grounded.
Note 4: Left/right signal-path gain is defined as:
MONO signal-path gain is defined as:
Note 5: MONO gain offset is measured with respect to speaker-path gain.
Note 6: Speaker mode testing performed with an 8
resistive load in series with a 68H inductive load connected across BTL output.
Headphone mode testing performed with a 32
resistive load connected between HP_ and GND. Mode transitions are controlled
by SHDN.
Note 7: Headphone-path gain is defined as:
Note 8: Guaranteed by design only.
