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 V
CC
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 µF to
1000 µF output-coupling capacitor (Figure 2–5).
