Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MP4865AGBD is a 64-channel, high-voltage, single-pole single-throw (SPST) analog switch with integrated output bleed resistors. The device can multiplex the transmit and receive voltages to and from multiple piezoelectric transducers (PZTs), and is designed for medical ultrasound imaging applications.

The output switches are controlled by a 64-bit serial shift register, followed by a 64-bit data latch. The data out pin (DOUT) allows for multiple devices to be cascaded together. This helps to minimize the number of input/output (I/O) control lines. When the data latch is logic high, the corresponding analog switch turns on; when the data latch is low, the corresponding switch turns off.

The MP4865A does not require any high-voltage supplies. It only requires two low-voltage supplies (3.3V and 5V). The analog switch can block or pass analog voltages up to ±90V with peak currents up to ±1.8A.

Applications

• Medical Ultrasound Imaging

• Non-Destructive Testing (NDT)

• 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.
