The TPA2012D2 EVM is a Pb-free, highly-efficient, filter-free stereo audio power amplifier evaluation module. It consists of the TI TPA2012D2 1.65 W low-voltage stereo Class-D audio power amplifier IC in a very small NanoFree™ wafer chip scale package (WCSP). All devices including the printed-circuit board are Pb free. Additionally, no lead is used in the manufacturing or assembly of the module. It is ideal for small battery operated electronics including wireless or cellular handsets and personal digital assistants (PDAs).
