2.3 Quick Start List for Stand-Alone
Follow these steps to use the TPA6010A4 EVM stand-alone or when
connecting it into existing circuits or equipment. Connections to the
TPA6010A4 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. 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 to 5 V to the module VDD
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 (left) positive lead of the audio source to the module
RLINE (LLINE) pins and the negative lead to the RIN (LIN) pins. If using
the headphone inputs, connect the positive audio source to the module
RHP (LHP) and the negative lead to RIN (LIN). The inputs can be used
with a differential or single-ended audio source, but the headphone and
line have common positive inputs.
5) If PCBEEP is to be used, a dc-blocked 1-V p–p 1-kHz square wave may
be applied to the EVM PCBEEP test point (TP1). (See the TPA6010A4
audio amplifier data sheet (TI lit number SLOS268) for more information.)
6) Select output mode:
a) For BTL output, connect a speaker to the module OUT+ and OUT–
pins of each channel, (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).
or
c) Connect a line-level load to the EVM LDOCK and RDOCK terminals
that is
no less than 1-k
Ω
and is dc-blocked
.
