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. See the data

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. However, the audio amplifier evaluation module can be used stand-alone by making connections directly to the module pins, and can be wired directly into existing circ
