C1 = 1µF, C2 = 1µF. T
Note 1: All devices are 100% tested at T
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:
Note 5: MONO gain offset is measured with respect to speaker-path gain.
Note 6: Speaker mode testing performed with an 8Ω resistive load in series with a 68µH inductive load connected across BTL output.
Note 7: Headphone-path gain is defined as:
Note 8: Guaranteed by design only.
