The TPA6205A1DRB audio power amplifier evaluation module is a complete, low-power single-channel
audio power amplifier. It consists of the TI TPA6205A1DRB 1.25-W low-voltage audio power amplifier IC
in a very small DRB package, along with a small number of other parts mounted on a circuit board that is
approximately one and a quarter inches square (see
Figure 1 ).
