otherwise noted. Typical values are at T
Note 1: All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 2: PSRR is specified with the amplifier input connected to GND through R
Note 3: Output power levels are measured with the TQFN’s exposed paddle soldered to the ground plane.
Note 4: Speaker path gain is defined as: A
Note 5: Speaker mode testing performed with 8Ω resistive load connected across BTL output. Headphone mode testing per-
Note 6: Headphone path gain is defined as: A
Note 7: See Table 3 for detains on the mute levels.
Note 8: Attack envelope is exponential. Attack time is defined as the 15 x 10
Note 9: Time for the gain to return to within 10% of nominal gain setting after the input signal has fallen below the PREF threshold.
Note 10: Dropout voltage is defined as (V
