Description 1.1 Description The TPA6017A2 audio power amplifier evaluation module is a 2-watt per channel class-AB stereo audio power amplifier complete with a small number of external components mounted on a circuit board that measures approximately 2-1/4 inches by 1-1/2 inches (Figure 1–1 and Figure 1–2). Figure 1–1. The TI TPA6017A2 Audio Power Amplifier EVM—Top View Figure 1–2.
TPA6017A2 EVM Specifications The plug-n-play platform has room for a single TPA6017A2 evaluation module and is convenient for evaluating the TPA6017A2 device. The EVMs simply plug into the platform, which provides power to the modules and connects them to a versatile array of standard audio input and output jacks and connectors. There is nothing to build, nothing to solder, and nothing but the speakers included with the platform to hook up. 1.2 TPA6017A2 EVM Specifications Supply voltage range, VDD . . .

Quick Start List for Plug-n-Play Platform 2.1 Quick Start List for Plug-n-Play Platform Follow these steps when using the TPA6017A2 EVM with the TI plug-n-play audio amplifier evaluation platform (see the platform user’s guide, literature number SLOU011, for additional details). Numbered callouts for selected steps are shown in Figure 2–1. - Platform Preparations 1) Ensure that all external power sources are set to OFF and that the platform power switch S1 is set to OFF.
Quick Start List for Plug-n-Play Platform 3) Connect speakers to left and right RCA jacks J7 and J9 or to stripped wire speaker connectors J8. - Evaluation Module Settings 1) Use jumpers J1 and J2 to set the gain of the TPA6017A2 amplifier (see Table 2–2 callout). Refer to Table 2–2 for gain settings. Table 2–2. Gain Settings GAIN0 (J1 jumper) GAIN1 (J2 jumper) Gain ON ON 6 dB ON OFF 10 dB OFF ON 15.6 dB OFF OFF 21.
Quick Start List for Stand-Alone Operation 2.2 Quick Start List for Stand-Alone Operation Follow these steps to use the TPA6017A2 EVM stand-alone or when connecting it into existing circuits or equipment. Connections to the EVM 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. - Power Supply 1) Ensure that all external power sources are set to OFF.
