TPA3255 Digital Audio Amplifier Board Easy to Install Efficient stereo Module Description: [Design]: TPA3255 is a high-performance Class D power amplifier chip with Class D performance and circuitry, which can provide true high-end sound quality. [Function]: The device features advanced integrated feedback design and patented high speed gate error correction. This technology allows the device to maintain a low level of distortion throughout the audio frequency band while demonstrating sound quality. [Details]: The car amplifier board operates in AD mode and can handle do 2 loads of 315 W/4R and 2 loads of 150 W (uncut power)/8R at THD of 1,5% and has an analog 2VRMS input interface for stable performance Seamless DAC connection (such as PCM5242 TI). [Function]: In addition to audio performance, the TPA3255 combines high energy efficiency with low power losses in idle state (less than 2,5W). This is achieved with MOSFET 85 mR transistors and an optimized gate scheme. [Size]: 122 mm x 73 mm x 30 mm / 48,03 inch x 2,87 inch x 1,18 inch Specification: Input method: stereo 3,5 mm (3P) wired socket interface Efficiency>90% Output power: Distortion 315 W/4Q 1,5% Distortion 185W/8Q 1,5% Distortion 260 W/4Q 1% Distortion 150W/8Q 16 Frequency Response: 20Hz do 20KHz Range>100dB Ratio>111dB Power supply: DC19 do DC50V [recommended current do 5A] The package includes: 1 car audio amplifier board
