TPA6203A1 Audio Power Amplifier Evaluation Module
The TPA6203A1 audio 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.
