Size 122mm x 73mm x 30mm / 48.03inx2.87inx1.18in Detail The car amplifier board operates in ad mode and can drive up to 2 315w/4r loads and 2 150w (unclipped power)/8r loads at a thd of 1.5%, and has a 2vrms analog input interface to support stable performance dac (such as ti's pcm5242) seamless connection. Feature Advanced integrated feedback design and proprietary speed gate driver error correction. This technology allows the device to maintain low distortion across the entire audio frequency band while demonstrating sound quality. Function In addition to audio performance, the tpa3255 combines power efficiency with low power level idle losses (less than 2.5w). This is achieved with 85mr mosfets and an optimized gate driver scheme. Use scenarios Fourchannel car audio system: Use this board to drive up to two 315W per channel at 4 ohms and two 150W per channel at 8 ohms, delivering dynamic range with a THD of 1.5% for demanding automotive audio setups. DACconnected installations: The 2V RMS analog input interface enables stable performance when paired with DACs such as TI PCM5242, allowing clean, seamless integration with external digitaltoanalog converters. Energyconscious or compact deployments: The design emphasizes efficiency and idle power under 2.5W, reducing heat and power draw in standby or lowload conditions while maintaining strong audio performance.
