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 circuits or equipment.

The TI Plug-N-Play platform supplies a 5-V regulated voltage that is designed to allow devices with an SE/BTL pin to automatically switch to SE output mode when a headphone is inserted into the headphone jack. The SE/BTL pin on the TPA6030A4 is designed to switch high when the voltage applied to the pin meets or exceeds 0.8 VCC, requiring a minimum of 5.6 V when the power supply is at 7 V. This is more than the platform can supply, and consequently, the automatic SE/BTL toggle feature of the TI Plug-N-Play platform is not fully compatible with the TPA6030A4EVM. However, the output mode can be manually changed with the use of J1 on the TPA6030A4EVM (see Table 2–2).

Refer to the application section of the TPA6030A4 data sheet for more information about building a circuit that automatically switches output modes when a headphone is inserted.

The jumper and switch settings on the TI Plug-N-Play platform do not change with different VCC levels.
