Using imported TPA3250 <br />2. The main circuit of the electrolytic capacitor signal adopts a chip electrolytic capacitor with a capacity of 4*220UF, which ensures a strong and continuous power support. <br />3. The resistors use high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine. <br />4. The PCB adopts 1.6m thick double-sided sheet, 2.0 oz copper thickness, and the whole process of spraying tin to ensure good passing performance of large and small currents. Top-notch PCB quality. <br />5. Fully shielded high-current inductors are used to ensure clear and powerful sound. <br /> <br />The TPA3250 device is a high-performance Class-D power amplifier that delivers true high-quality sound with Class-D efficiency. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (Purepath Ultra-HD). This technology enables ultra-low distortion and superior audio quality in the audio frequency band. The device operates from a 32V supply Power supply, can provide up to 2W*130W peak drive to 4ohm load, or 2W*70W continuous drive to 8ohm load, and has 2 VRMS analog input interface, which can be seamlessly matched with high-performance DACs such as TI PCM5242. Audio performance, the TPA3250 also achieves high power efficiency and power stage no-load power dissipation below 1 W. This is achieved by using 60 mohm MOSFETs and an optimized gate driver scheme with much lower no-load losses than typical discrete devices. <br />How it works: Class D <br />Quiescent current: 50mA <br />Work efficiency: 90% <br />Rated output power: 2x130W <br />Frequency Response: 20Hz to 20KHz <br />Working voltage: D18V to Dc32V <br />Maximum output current: 4A <br />Product size: length 103 x width 78 x height 15MM <br />Cable length: 30cm <br />Cable terminal specification: XH2.54mm-3P <br />Colour:black <br />Material:PCB+Metal <br /> <br />Package Contents: <br />1 x TPA3250 digital power amplifier board <br />1 x Audio signal cable <br /> <br />Only the above package content, other products are not included. <br />Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. </div></span> </div> </div> <div id="details"> <div class="ui-box-body"> <span style="font-size:18px;"> <table border="0" cellpadding="0" cellspacing="0" style="width: 100.0%;"> <tbody> <tr> <td style="margin: 0 auto; text-align: center;"><p></p><p></p><p></p><p></p><p></p><p></p></td> </tr> </tbody> </table> </span> <br /> <p> <br /> </p> <p> </p> </div> </div> </div></div></div>
