TI-3255 Balanced Class D Amplifier

TI-3255 Balanced and Single Ended Class D Audio Power Amplifier

This is our new TI (Texas Instruments) Class D power amplifier module based on the TPA3255. Our version of this amp features a super high quality 4 layer PCB with gold plating. We're using very high quality components in this amplifier. Features analog balanced and single ended inputs, adjustable clock, stereo or bridge mode, and a hybrid feedback design.

TPA3255 is a high performance class-D power amplifier that enables true premium sound quality
with class-D efficiency. It features an advanced integrated feedback design and proprietary highspeed gate driver error correction (PurePath™ UltraHD). This technology allows ultra low distortion across the audio band and superior audio quality. The device is operated in AD-mode, and can drive up
to 2 x 315 W into 4-Ω load at 10% THD and 2 x 150 W unclipped into 8-Ω load and features a 2 VRMS
analog input interface that works seamlessly with high performance DACs such as TI's PCM5242. In
addition to excellent audio performance.
