The device features advanced integrated feedback design and proprietary high-speed gate driver error correction function (PurePath TM Ultra HD). This technology enables the device to maintain ultra-low distortion throughout the entire audio frequency band while exhibiting perfect sound quality. The device operates in AD mode and can drive up to 2 315W\/4 Ω loads and 2 150W (uncut power)\/8 Ω loads at a THD of 10%. It also has a unique 2 VRMS analog input interface that supports seamless connection with high-performance DACs (such as TI's PCM5242). In addition to excellent audio performance, TPA3255 also has high power efficiency. Two major advantages are ultra-low power idle loss (less than 2.5W). This can be achieved through an 85m Ω MOSFET and an optimized gate driver scheme. Compared to traditional discrete implementation schemes, this scheme can significantly reduce idle loss.\u003c\/p\u003e \n\u003c\/div\u003e\n\u003cdiv class=\"detailmodule_image\"\u003e\n \u003cimg class=\"detail-desc-decorate-image\" data-id=\"ckeditor_img39\" referrerpolicy=\"no-referrer\" slate-data-type=\"image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S4b58d77e705f4b70a0d629ae44cb20008.jpg\"\u003e \n \u003cimg class=\"detail-desc-decorate-image\" data-id=\"ckeditor_img40\" referrerpolicy=\"no-referrer\" slate-data-type=\"image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S6b9113d36e31435896ac27579b66da64x.jpg\"\u003e \n \u003cimg class=\"detail-desc-decorate-image\" data-id=\"ckeditor_img41\" referrerpolicy=\"no-referrer\" slate-data-type=\"image\" src=\"https:\/\/ae01.alicdn.com\/kf\/S19fd07463ba941c090879dcde5f5f6eb8.jpg?width=1300\u0026amp;height=1300\u0026amp;hash=2600\"\u003e \n \u003cimg class=\"detail-desc-decorate-image\" data-id=\"ckeditor_img42\" referrerpolicy=\"no-referrer\" slate-data-type=\"image\" src=\"https:\/\/ae01.alicdn.com\/kf\/Sa01af205e5914efb8b567c0ee42545208.jpg\"\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"detailmodule_text\"\u003e \n \u003cp style=\"font-size:13px;font-weight:bold\"\u003eInspection Process:\u003c\/p\u003e \n \u003cp class=\"detail-desc-decorate-content\" style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\"\u003eBefore unpacking, it is necessary to record the appearance of the package and the unpacking process with a full video recording;\u003cbr\u003e Exception handling: If damage or pressure marks are found on the courier packaging, the following evidence should be taken and feedback should be provided within 24 hours:\u003cbr\u003e 1.
