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 high speed gate driver error correction (PurePath™ Ultra-HD).
1 paź 2021 · Gain is calculated so that a 4Vrms input signal (+/- 14dBu) maxes the tpa3255 input (once the pffb is taken into account), with 3dB of excess gain. Actually a bit more than that in practice since I won't run the tpa3255 at max voltage.
This technology allows ultra-low distortion across the audio band and superior audio quality. TPA3255/TPA3255-Q1 is operated in AD-mode and can drive up to 2x315W into the 4Ω load at 10% THD and 2x150W unclipped into the 8Ω load.
260-W Stereo into 4 Ω in BTL Configuration. 150-W Stereo into 8 Ω in BTL Configuration. 480-W Mono into 2 Ω in PBTL Configuration. Advanced Integrated Feedback Design with High-speed Gate Driver Error Correction (PurePathTM Ultra-HD) Signal Bandwidth up to 100 kHz for High Frequency Content From HD Sources.
24 lut 2016 · I'm building a 3-way active speaker. I'd like to power each driver with an individual TPA3255 channel. So the options I see: - buy one 2-channel TPA3255 board for the mid and high driver, and a 1-channel board for the subwoofer driver... or - buy a 4-channel TPA3255 board to power 3 drivers and leave one channel unused.
