Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD4858BBCZ is a fully buffered, 8-channel synchronous sampling, 20-bit, 1 MSPS data acquisition system (DAS) with differential, wide common-mode range inputs.The AD4858 is powered by a low 5 V supply, a flexible input buffer supply, and uses a precision, low-drift internal reference and reference buffer, which allows for independently configurable SoftSpan ranges for each channel to match the Native application signal swing to minimise additional external signal conditioning. To further maximise single-conversion dynamic range, the AD4858 uses Seamless High Dynamic Range (SHDR) technology. When this technology is enabled, the channel's input signal path gain is automatically optimised on a sample-by-sample basis to minimise converter noise on a per-sample basis without compromising linearity.

The AD4858BBCZ features a 7.00 mm × 7.00 mm, 64-ball, ball grid array (BGA), including all critical power and reference bypass capacitors, minimising the footprint and component count of the overall solution and reducing sensitivity to the application's printed circuit board (PCB) layout. It operates over the -40°C to +125°C temperature range.

Test and Measurement

• 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.
