Note 1:
All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 2:
Inputs AC-coupled to GND.
Note 3:
The device is current limited. The maximum output power is obtained with an 8
load.
Note 4:
Testing performed with an 8
resistive load in series with a 68μH inductive load connected across BTL outputs. Mode tran-
sitions are controlled by
SHDN
