The TPA0202 Audio Power Amplifier Evaluation Module
The TPA0202 Audio Power Amplifier Evaluation Module is powered by a
TPA0202 stereo power amplifier capable of delivering greater than 2 W of
continuous power per channel into 3-
Ω
loads. The amplifier IC can be operated
in either the BTL or single-ended output mode. The evaluation module
includes control inputs for muting and shutdown, selection between two sets
of stereo inputs, and switching between single ended and bridge-tied load
output modes.
The module can be used with the TI Plug-N-Play Audio Amplifier Evaluation
Platform (Figure 3 –1) or wired directly into circuits or equipment. The module
has single in-line header connector pins mounted to the under side of the
board. These pins allow the module to be plugged into the TI platform, which
automatically makes all the signal input and output, power, and control
connections to the module.
The module connection pins are on 0.1-inch centers to allow easy use with
standard perf board and plug board-based prototyping systems. Or, the EVM
can be wired directly into existing circuits and equipment when used stand-
alone.
The module appears in Figure 3–2 and its schematic is shown in Figure 3 – 3.
