The TPA3255 Audio Amplifier Module is a high-power Class-D audio amplifier based on the Texas Instruments TPA3255. It is designed for high-performance audio applications including home audio systems, powered speakers, soundbars and subwoofers. The TPA3255 supports an 18V to 53.5V power-stage supply and can deliver up to 2×315W into 4Ω or 600W mono into 2Ω under specified test conditions.

Full Description

The TPA3255 Audio Amplifier Module uses Texas Instruments' high-performance Class-D TPA3255 amplifier technology, combining high output power with high efficiency and low distortion.

The TPA3255 supports multiple amplifier configurations including stereo, mono and 2.1, making it suitable for a wide range of high-power audio projects. The device offers approximately 90% efficiency at 4Ω and features very low distortion, with 0.006% THD+N at 1W into 4Ω under the specified test conditions.

The amplifier can provide up to 2×260W into 4Ω at 1% THD+N, or 2×315W into 4Ω at 10% THD+N. In mono/PBTL configuration, the device can reach up to 480W into 2Ω at 1% THD+N or 600W into 2Ω at 10% THD+N.

Technical Specifications

Core specifications are based on the Texas Instruments TPA3255 datasheet; connector layout, board dimensions and actual module output depend on the specific amplifier module design.
