The TPA2010D1 EVM is a Pb-free, highly-efficient, filter-free mono audio power amplifier evaluation module. It consists of the TI TPA2010D1 2.5-W low-voltage 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).
