TPA3002D2
：
The TPA3002D2 is a 9-W (per channel) efficient, Class-D audio amplifier for driving bridged-tied stereo
speakers. The TPA3002D2 can drive stereo speakers as low as 8 . The high efficiency of the TPA3002D2
eliminates the need for external heatsinks when playing music.
Main Features
：
●
9W /Ch into an 8
Ω
load from 12Vsupply;
●
Efficient, class D operation eliminates heatsinks and reduces power supply requirements;
●
32-step DC volume control from -40db~36db;
●
Line outputs for external headphone;
●
Thermal and short-circuit protection

MODE
Input for MODE control. A logic high on this pin places the amplifier in
the variable output mode and the Class-D outputs are disabled. A logic
low on this pin places the amplifier in the Class-D mode and Class-D
stereo outputs are enabled. Variable outputs (VAROUTL and
VAROUTR) are still enabled in Class-D mode to be used as line-level
outputs for external amplifiers.

MODE_OUT
Output for control of the variable output amplifiers. When the MODE pin
