1.2 Description
The TPA6203A1 audio power amplifier evaluation module is a complete, low-power single-channel audio
power amplifier. It consists of the TI TPA6203A1 1.25-W low-voltage audio power amplifier IC in a very
small MicroStar Junior™ BGA package, along with a small number of other parts mounted on a circuit
board that is approximately one and a quarter inches square.

2 Operation
Follow the steps in this chapter to prepare the TPA6203A1 audio amplifier EVM for use. The audio
amplifier evaluation module is a stand-alone unit and can be used by making connections directly to the
module pins, and it can be wired directly into existing circuits or equipment.
2.1 Quick-Start List
Follow these steps to use the TPA6203A1 EVM stand-alone or when connecting it into existing circuits or
equipment. Connections to the TPA6203A1 module header pins can be made via individual sockets,
wire-wrapping, or soldering to the pins, either on the top or the bottom of the module circuit board.
