China Lonten TAP3116D2 2.0 Stereo Double Channel HiFi High Power Digital Amplifier Board DC 12V To 22V

Lonten provide electronic component ,welcome OEM ,ODM,for more please contact.

Description: The power amplifier board adopts one piece of TI's latest digital chip TPA3116D2 to do the power amplification of the left and right channels, and the efficiency is up to 90%. It has the characteristics of small size, high efficiency, high power and low heat generation. The pre-stage circuit uses NJM4580 for small signal processing. This freight has extremely low distortion, very low noise and high bandwidth. The treble is clear and the bass is powerful. The material is not used for cost. It is filtered by black diamond high frequency and low resistance. Taiwan-made sealed high-quality potentiometer, original chip, new SMD chip device, green slotted radiator. The board is beautiful and stable, and the work is stable and reliable. Technical Parameters: Supply voltage: DC 12V-22VMaximum output power: 2X50WEfficiency: >=90%Signal to noise ratio: 100dBTotal harmonic distortion: (50W/1KHz/24V/4--0.1%) (30W/1KHz/24V/8--0.1%)Frequency response range: 20Hz-20KHzInput impedance: 30KSpeaker: 4-8Voltage gain: 26dBPotentiometer center distance: 25mmPower amplifier board size: 60mm*48mm*16mm (the size includes the potentiometer handle protruding part)Weight: 35 g Note: 1. The power supply limit voltage is 24V, please do not exceed! Otherwise, the capacitor is easy to burst, and the peak value of the voltage used for AC rectification should not exceed 25V. Do not supply power above this voltage. Reverse the positive and negative poles.2. The power supply is recommended to supply 22V/5A or better. The lower the voltage, the smaller the power. Many use 12V power supply, saying that the power is insufficient. In fact, the power is only about 2*15W.3. Speaker recommended 40-80W speaker4. Do not short the o output to each other or to the ground5. Please check carefully before powering on to ensure that the wiring is correct. Package Included: 1 x TAP3116D2 Digital Amplifier Board
