Introduction
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 (see Figure 1–1).

†Due to the very small size of the MicroStar Junior BGA IC package, the standard part number
TPA6203A1 is replaced with the code AADI.
Single in-line header pins are mounted to the underside of the module circuit
board. These pins allow the EVM to be plugged into the TI plug-n-play audio
amplifier evaluation platform or to be wired directly into existing circuits and
equipment when used stand-alone.
The platform, which has room for a pair of TPA6203A1 evaluation modules,
is a convenient vehicle for demonstrating TI’s audio power amplifier and
