TPA3255 is a high
performance class D power amplifier chip, which has class D efficiency and can
bring true high-end sound quality circuit. The device features advanced
integrated feedback design and proprietary high-speed gate driver error
correction function (PUREPATH) ™ UHD).
This technology enables the device to maintain ultra-low distortion over the
entire audio frequency band while displaying perfect sound quality. The device
works in AD mode. When thd is 10%, the device can drive up to two 315w / 4R
loads and two 150W (uncut power) / 8R loads, and has a 2 VRMs analog input
interface, which supports seamless connection with high-performance DAC (such
as TI's pcm5242). In addition to its excellent audio performance, tpa3255 has
the advantages of high power efficiency and ultra-low power level idle loss
(less than 2.5W). This can be achieved with an 85mr MOSFET and an optimized
gate driver scheme. Compared with the traditional discrete implementation
scheme, this scheme can significantly reduce the idle loss.
