Product Specification

Product Description:

TPA3251D2 is a high-performance class D power amplifier, which has class D efficiency and can bring true high-end sound quality. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath Ultra HD). This technology allows the device to maintain ultra-low distortion throughout the audio frequency band while exhibiting perfect sound quality. The device can drive up to two 175W /4Ω loads and two 220W /3Ω loads, and has a 2 VRMS analog input interface that supports seamless connection with high-performance DACs (for example, TI's PCM5242). In addition to excellent audio performance, TPA3251D2 also has two major advantages: high power efficiency and ultra-low power level idle loss (below 1W). This can be achieved using 60mΩ MOSFETs and an optimized gate driver solution, which can significantly reduce idle losses compared to traditional discrete implementations.

Features:

1. Using original TPA3251D2
2. The main filter electrolytic capacitor adopts imported famous brand capacity 4700UF/63Vx2 to ensure strong and continuous power support.
3. High-precision chip resistors are selected for the resistors to ensure a good signal-to-noise ratio of the whole machine.
4. Use special inductance for audio to ensure clear and powerful sound.
5. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. First-class PCB quality.
