Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TAS6424LQDKQRQ1 device is a 4-channel digital input Class D audio amplifier designed specifically for car audio head units and external amplifier modules. Under a 14.4V power supply voltage, when the load is 4Ω and THD+N is 10%, the device can provide 27W of output power across all four channels; when the load is 2Ω and THD+N is 10%, the device can deliver 27W of output power. Compared to traditional linear amplifier solutions, D-class topology technology significantly improves device efficiency. The output switching frequency can be set above the amplitude modulation (AM) band to eliminate AM band interference and reduce output filtering requirements and costs; it can also be set below the AM band to optimise device efficiency.

The wide power supply voltage range of 4.5V to 18V helps minimise audio distortion in start-stop applications.

The TAS6424LQDKQRQ1 integrates all the features required for demanding OEM applications. The device includes built-in load diagnostic functionality to detect and diagnose misconnected outputs, as well as detect AC-coupled high-frequency speakers, helping to reduce test time during manufacturing.

The TAS6424LQDKQRQ1 is available in a 56-pin HTSSOP PowerPAD™ package with an exposed thermal pad facing upward.

Applications for TAS6424LQDKQRQ1

• Car audio head units

• Car external amplifier modules

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
