Audio Measurement Systems
The TPA3003D2 uses a modulation scheme that does not require an output filter for operation, but they do
sometimes require an RC low-pass filter when making measurements. This is because some analyzer inputs
cannot accurately process the rapidly changing square-wave output and therefore record an extremely high
level of distortion. The RC low-pass measurement filter is used to remove the modulated waveforms so the
analyzer can measure the output sine wave.
