Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD4851BBCZ is a fully buffered, 4-channel synchronous sampling, 16-bit, 250kSPS data acquisition system (DAS) with differential and wide common-mode range input. The AD4851BBCZ is powered by a 5V low-voltage power supply and a flexible input buffer power supply. It uses a precise low-drift internal reference and reference buffer, allowing the SoftSpan range of each channel to be independently configured to match the application signal swing, thereby minimizing additional external signal conditioning.

To further maximize the dynamic range of single conversion, the AD4851BBCZ adopts seamless High Dynamic Range (SHDR) technology. After being enabled, the input signal path gain of the channel will be automatically optimized on a sample basis, thereby minimizing the converter noise on each sample without affecting the linearity.

Its main features include:

A complete 16-bit data acquisition system

Four internal buffer channels are sampled synchronously

The throughput of each channel is 250kSPS

Differential input with a wide common mode range

The typical input leakage at 25°C is ±75pA

The step establishment time for full-scale input is less than 300 ns

Integrated reference and reference buffer (4.096V)

Integrated power decoupling capacitor

At 250kSPS, each channel has 36mW, and the power scales with the throughput

There is very little external signal conditioning

Seamless high dynamic range

Automatic gain range for each sample and each channel

Maintain ppm level INL

Each channel's SoftSpan input range is either bipolar or unipolar

Application scenarios

The AD4851BBCZ is suitable for application scenarios that require high-precision and high-speed data acquisition, such as industrial control, test and measurement, and instrumentation. Its high performance and low power consumption make it excel in demanding industrial applications ‌.

• 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.
