EMIand AGL
1 Features 3 Description The TPA3140D2 is an efficient, Class-D audio power
amplifier for driving bridged-tied stereo speakers at
up to 10 W, 6 Ω, or 8 Ω (per channel). 1 2x10 W/ch into 6-Ω Loads at 10% THD+N from a
12-V Supply
2x10 W/ch into 8-Ω Loads at 10% THD+N from a
13-V Supply
Up to 90% Efficient Class-D Operation (8 Ω)

(4) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The voltage slew rate of these pins must be restricted to no more than 10 V/ms. For higher slew rates, use a 100 kО© resister in series …
