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.

Total Output Power at 10%THD+N – 315-W Stereo into 4 Ω in BTL Configuration – 185-W Stereo into 8 Ω in BTL Configuration – 600-W Mono into 2 Ω in PBTL Configuration • Total Output Power at 1%THD+N – 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 Highspeed Gate Driver Error Correction (PurePath™ Ultra-HD) – Signal Bandwidth up to 100 kHz for High Frequency Content From HD Sources – Ultra Low 0.006% THD+N at 1 W into 4 Ω and <0.01% THD+N to Clipping – >65 dB PSRR (BTL, 1 kHz, No Input Signal) – <85 µV (A-Weighted) Output Noise – >111 dB (A Weighted) SNR • Multiple Configurations Possible: – Stereo, Mono, 2.1 and 4xSE • Click and Pop Free Startup and Stop • 90% Efficient Class-D Operation (4 Ω) • Wide 18-V to 53.5V Supply Voltage Operation • Self-Protection Design (Including Undervoltage, Overtemperature, Clipping, and Short Circuit Protection) With Error Reporting

    I read some positive comments and reviews on this chip so I decided to order a board to upgrade my old SDS amp.

    The board I received was not exactly as pictured. It had rca inputs between the balanced inputs. Instead of screw terminals for left and right output and power in it had 9 inch or so wires soldered to the board. It seems to be well made and has a label on the board that says “made in USA”.

    I managed to fit it into my old SDS amplifier chassis. Without screw terminals for input I had to come up with a kludge to connect my panel mounted rca sockets.to the board.

    I have spent a good deal of time listening to various types of music and I have been impressed so far.. I do not hear any artifacts that would make me aware I was listening to a class d amp. High frequency reproduction seems excellent to me. It seems very neutral in how it sounds. Not warm sounding or cold sounding at all. I plan on keeping iit n my system.

    I think I will buy another enclosure and mount the board so that the inputs will protrude through the back panel.

    Is it helpful?
