Page 2: Feature Highlights
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... - Page 3 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 TPA6205A1DRB evaluation modules, 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.

11. Adjust the signal source level as needed. Quick Start List for Stand-Alone Follow these steps to use the TPA6205A1DRB EVM stand-alone or when connecting it into existing circuits or equipment. Connections to the TPA6205A1DRB 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. - Page 7 6. Connect an 8Ω–32Ω speaker to the module OUT+ and OUT– pins. Power-Up Procedure 7. Verify correct voltage, input polarity; set external power supply to on. The EVM begins operation. 8. Adjust the signal source level as needed. SLOU182 – MAY 2006 TPA6205A1DRB Audio Power Amplifier EVM Submit Documentation Feedback...
