1.2 Description
The TPA152 Audio Power Amplifier Evaluation Module is a complete,
low-power stereo audio power amplifier for high-fidelity line-level output and
headphone applications. It consists of the TI TPA152 75-mW Stereo Audio
Power Amplifier IC in a very small package, along with a small number of other
parts mounted on a circuit board that is approximately one and a quarter
inches square (Figure 1–1).
Figure 1–1. The TI TPA152 Audio Amplifier Evaluation Module
Single in-line header pins are mounted to the underside of the module circuit
board to 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 has room for a single TPA152 evaluation module and is a
convenient vehicle for demonstrating TI's audio power amplifier and related
evaluation modules. The EVMs simply plug into the platform, which
automatically provides power to the modules, interconnects them correctly,
and connects them to a versatile array of standard audio input and output jacks
and connectors. Easy-to-use configuration controls allow the platform and
EVMs to quickly model many possible end-equipment configurations.
There is nothing to build, nothing to solder, and nothing but the speakers
included with the platform to "hook up."
