Feature Highlights 1.
Description 1.2 Description The TPA6030A4 stereo 3-W audio power amplifier evaluation module is designed to demonstrate all of the different features and benefits of the TPA6030A4 amplifier. It consists of the TI TPA6030A4 stereo 3-W audio power amplifier IC along with a small number of other parts mounted on a circuit board that measures approximately 2 1/4 inches by 1 1/2 inches (Figure 1–1). Figure 1–1.
Special Notes Regarding the Data Sheet 1.4 Special Notes Regarding the Data Sheet The TPA6036A4EVM may have markings not consistent with the data sheet. Some EVMs have an incorrect supply voltage marked on them. The correct supply range is 7 V to 15 V, not 5 V to 15 V. The EVM and this user’s guide refer to the two input pins as HP and LINE, and refer to the control pin as HP/LINE. The data sheet refers to the two inputs as IN2 and IN1, respectively, and the control pin as IN2/IN1.
Chapter 2 Quick Start The steps in this chapter can be followed to quickly prepare the TPA6030A4 audio amplifier EVM for use. Using the TPA6030A4 with the TI Plug-N-Play audio amplifier evaluation platform is a quick and easy way to connect power, signal and control inputs, and signal outputs to the EVM using standard connectors.

Table 2–2.
Precautions 2.1 Precautions Power Supply Input Polarity and Maximum Voltage Always ensure that the polarity and voltage of the external power connected to VCC power input connector J1, J2, and/or VDD power input connector J6 are correct. Overvoltage or reverse-polarity power applied to these terminals can open onboard soldered-in fuses and cause other damage to the platform, installed evaluation modules, and/or the power source.
Quick Start List for Platform 2.2 Quick Start List for Platform Follow these steps when using the TPA6030A4EVM with the TI Plug-N-Play audio amplifier evaluation platform (see the platform user’s guide, SLOU011, for additional details). Numbered callouts for selected steps are shown in Figure 2–1 and Figure 2–2: Note: The TI Plug-N-Play platform sends the input signal to both the HP and LINE inputs automatically, and only to the positive inputs.
Quick Start List for Platform - Evaluation Module Preparations Figure 2–2. Module Preparation 13 12 10 11 10) The SE jumper, J1, is used to select between the two output modes, SE and BTL. To allow the module SE/BTL control input to force the amplifier IC into a BTL output mode, set output mode jumper J1 to OFF. To keep the module amplifier IC in the single-ended output mode regardless of the control input state, set jumper J1 to ON.
Quick Start List for Stand-Alone 2.3 Quick Start List for Stand-Alone Follow these steps to use the TPA6030A4EVM stand-alone or when connecting it to existing circuits or equipment. Connections to the TPA6030A4 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. Numbered callouts for selected steps are shown in Figure 2–3. Figure 2–3.
Quick Start List for Stand-Alone - Evaluation Module Preparations 6) To force the EVM into a BTL output mode, set jumper J1 to OFF. To force the EVM into a SE output mode, set jumper J1 to ON. 7) To force the EVM into using the LINE inputs, set jumper J2 to OFF. To force the EVM into using HP inputs, set jumper J2 to ON.
