The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function. This technology allows the device to maintain ultra-low distortion throughout the audio frequency band while exhibiting perfect sound quality. The device can drive up to 2*175W \/ 4 loads or 2*220W \/ 3 loads, and has a 2 VRMS analog input interface that supports seamless connection with high-performance DACs (for example, TI's PCM5242). In addition to excellent audio performance, TPA3251D2 also has two major advantages: high power efficiency and ultra-low power level idle loss (below 1W). This can be achieved with a 60m MOSFET and an optimized gate driver solution, which can significantly reduce idle losses compared to traditional discrete implementations.Basic performance parameters:The total output power when the total harmonic distortion + noise (THD + N) is 10% .175W \/4 ohm , Bridge Tied Load (BTL) stereo configuration . 220w \/3 ohm , bridged load (BTL) stereo configuration . 350w \/2 ohm , parallel bridge load (PBTL) mono configuration .The total output power when THDN is 1%.140W \/4 ohm , BTL stereo configuration .175w \/3 ohm, BTL stereo configuration .285W \/2 ohm, PBTL mono configuration .Adopt advanced integrated feedback design, with high-speed gate driver error correction function.Single broadband up to 100kHz for high-frequency components of high-definition sources.Ultra-low THD +N: 0.005% at 1W \/4 ohm  \u0026lt;0.01% at clipping .60dB Power Supply Rejection Ratio (PSRR) (BTL, no input signal).\u0026lt;60uV (A-weighted) output noise .\u0026gt; 111dB (A-weighted) signal-to-noise ratio (SNR) .Specifications:Name: Amplifier BoardModel: TPA3251D2Working Voltage: DC24-36V Material: MetalSize: approx.15x9cm\/5.91x3.54inColor: As pictures shownQuantity: 1 PcNote:Please allow 0-1cm error due to manual measurement.","brand":"O2INEW","offers":[{"title":"Default Title","offer_id":1612203261967,"sku":"O2I-4-275233600661","price":17330.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0929\/2582\/products\/s-l1200__27431_991490df-3db4-464e-8e30-85b8047d63c6.jpg?v=1680056891","url":"https:\/\/order2india.com\/products\/tpa3251d2-digital-power-amplifier-board-175w-175w-stereo-hifi-audio-amplifer","provider":"ORDER2INDIA SHOPPING","version":"1.0","type":"link"}
