The TPA203XD1EVM is a Pb-free, highly-efficient, Filter-Free mono audio power amplifier evaluation module. It consists of the TPA2032D1, a 2.75 W low-voltage stereo Class-D audio power amplifier IC in a very small NanoFree™ wafer chip scale package (WCSP), and all necessary passive components. The TPA203XD1EVM also includes three snap-out mini-EVMs of the TPA2032D1, TPA2033D1 and the TPA2034D1. 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).
