Power 300W + 300W Class D O Digital Amplifier Board Updated Version

Buyers note: The product has 3 configurations to choose from!

Basic version: use NE5532P op amp

Upgraded version: use LME49720NA op amp

Deluxe version: use LME49720NA operational amplifier + nichicon FW 2200uF/63v fever audio electrolytic capacitor + WM capacitor

TPA3255 is a high-performance cla D power amplifier, it has cla D efficiency and can bring true high-end sound quality. The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath Ultra HD). This technology allows the device to maintain ultra-low distortion throughout the audio frequency band while exhibiting perfect sound quality. The device works in AD mode. When the THD is 10%, it can drive up to 2 315W/4R loads and 2 150W (unclipped power)/8R loads, and has a 2 VRMS analog input interface that supports high-performance DAC (For example, TI's PCM5242) seamle connection. In addition to excellent audio performance, TPA3255 also has two major advantages: high power efficiency and ultra-low power level idle lo (le than 2.5W). This can be achieved with an 85mR MOSFET and an optimized gate driver scheme. Compared with the traditional discrete implementation, this solution can significantly reduce idle lo.

product details: 1. Use TPA3255 2. The computing end uses the replaceable DIP-8 op amp *2, and buyers can upgrade the computing model independently. This product uses 2 TI high-performance audio operational amplifiers NE5532P 2. The main filter electrolytic capacitor adopts Nichicon capacity 2200UF/63V*2, 6 Nichicon FW series 10UF golden audio input coupling capacitors. Other filter capacitors use Nichicon series. 3. Adopt SAGAMI 7W14A inductor for audio digital cla D amplifier to ensure the sound is clear and powerful. Basic performance parameters: Working method: Cla D Standby current: 80mA Work efficiency:.>90% Channel: 2.0 Rest/mute: short circuit mute function Output Power: 315W/4Ω, distortion 10% 185W/8Ω, distortion 10% 260W/4Ω, distortion 1% 150W/8Ω, distortion 1% Frequency response: 20Hz to 20KHz Dynamic range: >100 dB Signal to noise ratio: (SNR)> 111dB Working voltage: DC24-40V switching power supply (recommended voltage 36V) PCB size: 110*70*36.5MM (small size, high power, more convenient DIY installation) version volume: 110*70*41MM (including capacitor) Net weight: 0.15KG
