TPA2011D1 Audio Power Amplifier Evaluation Module
The TPA2011D1 audio power amplifier evaluation module is a complete, low-power, Class-D, mono audio
power amplifier capable of delivering 1.47 W into 8
Ω
and 2.57 W into 4 ohms at 1% THD+N (YFF
package). All components and the evaluation module are Pb-free. The TPA2011D1 evaluation module
(EVM) consists of a TPA2011D1 device and all necessary components to evaluate it.
