Note 1:
All devices are 100% production tested at +25°C. 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 R

Note 4:
Speaker mode testing performed with an 8
resistive load in series with a 68μH inductive load connected across BTL out-
put. Headphone mode testing performed with 32
resistive load connected to GND. Mode transitions are controlled by
SHDN
. K

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.
