Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC6563IUDDM is a low-noise, four-channel transimpedance amplifier (TIA) with a 600MHz bandwidth.The LTC6563IUDDM TIA features low noise, a wide linear range, and low power consumption, making it ideally suited for LIDAR receivers utilizing avalanche photodiodes (APDs) and photodiodes (PDs). The amplifier has a selectable 22.2/16.7/11.1/5.55kΩ transimpedance gain (RT) and a 90μ linear input current range. It utilizes an APD with 0.5pF total input capacitance and has input current noise densities of 1.8pA/√Hz (at 100MHz) and 3.7pA/√Hz (at 600MHz). Depending on the output mode, the LTC6563IUDDM is powered from a 3.3V supply and consumes between 194mW and 325mW. An internal 4:1 MUX simplifies system design. In addition, the external multiplexing capability supports channel expansion of up to 64 channels, saving space and power consumption.The LTC6563IUDDM features fast overload recovery and fast channel switching, making it ideally suited for LIDAR receivers that integrate multiple APDs. The built-in high-speed differential ADC driver has a swing of up to 2VP-P when driving a 100Ω external differential load.

The LTC6563IUDDM is available in a 3mm × 5mm 24-pin exposed-pad QFN package with wettable flanks.

• 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.
