Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD7699BCPZRL7 is an 8-channel, 16-bit charge redistribution successive approximation register (SAR) analog-to-digital converter (ADC) that is powered by a single VDD power supply. The AD7699BCPZRL7 contains all the components for a multichannel, low-power data acquisition system, including an IC and an IC interface, including a true 16-bit SAR analog-to-digital converter; 8-channel low crosstalk multiplexer that can be configured as a single-ended (with or without ground sense) input, differential, or multiplexer. analogue-to-digital converter; and an 8-channel low crosstalk multiplexer with inputs configurable as single-ended (with or without ground sense), differential, or multiplexer. Internal 4.096 V low-drift reference and buffer; a temperature sensor; an optional single-pole filter; and sequencer useful when scanning channels sequentially. Sequencer, useful when scanning channels sequentially. the AD7699BCPZRL7 uses a simple serial port interface (SPI) for writing configuration registers and receiving conversion results. the SPI interface uses a separate power supply VIO, which is set to the host logic level. the SPI interface uses a separate power supply VIO, which is set to the The SPI interface uses a separate power supply VIO, which is set to host logic levels. Power dissipation is proportional to throughput. the AD7699BCPZRL7 is available in a miniature 20-lead LFCSP and a 20-ball WLCSP package with an operating temperature range of -12°C to +12°C. In the WLCSP, the operating temperature range is -40°C to +85°C. The AD7699BCPZRL7 is available in a miniature 20-lead LFCSP and a 20-ball WLCSP package with an operating temperature range of -40°C to +85°C.

• 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.
