The TPA2025D1EVM is an evaluation module for TPA2025D1, a mono 2W Class D audio amplifier with an integrated boost converter. The evaluation module comprises a TPA2025D1, a small number of external components, and input and output connectors to simplify interface to an audio source and speaker. The evaluation module features jumpers to easily select battery guard inflection point and fixed gain settings. The evaluation module supports filter free operation, and includes an optional on board RC filter to reduce measurement error when testing Class-D performance. The evaluation module allows quick evaluation of sound quality and loudness improvements. Designers will easily verify system performance.
