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.
