Audio Amplifier Board Module 600W High Power 2.0 Channel with 3.5mm Stereo Input Interface

features an integrated feedback design and high-speed gated driver error correction, allowing the device to maintain ultra-low distortion at audio bands while delivering high-quality sound.​

Features:​

Class D power amplifier chip with high operating efficiency, and this circuit can deliver truly high-end sound quality.

Fine circuit layout, with ТРА3255 high-performance chip, black crystal balanced audio inductors, professional op-amp capacitors, high-capacity audio professional filter capacitor, freely replaceable op-amps.

​The device features an integrated feedback design and high-speed gated driver error correction, allowing the device to maintain ultra-low distortion at audio bands while delivering high-quality sound.​

Operating in AD mode, the device can drive up to two 315W/4R loads and two 150W (unclipped power)/8R loads at 1.5% THD, and features a 2 VRMS analogue input interface for seamless connection to high-performance DACs such as TI's PCM5242.

In addition to high audio performance, the TPA3255 also combines high power efficiency and ultra-low power-level idle losses (less than 2.5W).

This is achieved with 85mR MOSFETs and an optimized gate driver scheme, which significantly reduces the idling loss.

High-density pure aluminum heat sinks, which dissipate heat faster for the same volumes.

With 3.5MM stereo wired socket connector (3P)
