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.

-Power Supply
1)Ensure that all external power sources are set to OFF.
2)Connect an external regulated power supply set from 7 V to 15 V to the module VCC and GND pins taking care to observe marked polarity.
-Inputs and Outputs
3)Ensure that audio signal source level adjustments are set to minimum.
4)Connect the right (or left) positive lead of the audio source to the module
R LINE+ (or L LINE+) pins and the negative lead to the R LINE– (or L LINE–) pins. If using the headphone inputs, connect the positive audio source to the module R HP+ (L HP+) and the negative lead to R HP– (L HP–).The inputs can be used with a differential or single-ended audio source. If stereo use is desired, connect both right and left inputs to the appropriate sources.
5)Select output mode:
a)For BTL output, connect a speaker to the module OUT+ and OUT– pins of each channel, (see Figure 2–4)
or
b)For single-ended output, connect a headphone or a speaker to the module OUT+ and GND pins of each channel through a 33 ∝ F to 1000 ∝ F output-coupling capacitor (Figure 2–5).
