TPA3255 Four-channel digital Class D amplifier board
TPA3255 is a high-performance Class D amplifier, which has Class D effectivity and may deliver true high-end sound high quality. There is a complicated built-in suggestions design and a proprietary high-speed gate driver error correction perform. This expertise permits the gadget to take care of ultra-low distortion all through the whole audio frequency whereas exhibiting good sound high quality.
