Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADAQ4381-4BBCZ is a four-channel precision data acquisition (DAQ) signal chain μModule solution that shortens the development cycle of precision measurement systems by shifting the challenges of component selection, optimisation and layout in signal chain design from the designer to the device.

The ADAQ4381-4BBCZ uses system-in-package (SIP) technology to integrate multiple general-purpose signal processing and conditioning modules into a single device, reducing the number of components in the end system. These modules include a quad-channel, high-resolution, 14-bit, 4 MSPS synchronous sampling SAR ADC, a low-noise, fully differential ADC drive amplifier, a 3.3 V precision voltage reference, a low-noise buffer amplifier, and a low dropout linear regulator.

The ADAQ4381-4BBCZ features an on-chip oversampling block to increase dynamic range and reduce noise at lower bandwidths. Oversampling adds up to two bits of resolution. It has the flexibility of a configurable ADC driver feedback loop that allows four gain and attenuation adjustments and accepts fully differential or single-ended to differential input configurations.

The ADAQ4381-4BBCZ uses Analog Devices, Inc. iPassives® technology, which integrates key passive components with excellent matching and drift characteristics to minimise temperature-dependent error sources and provide optimised signal chain performance. The ADAQ4381-4BBCZ is supplied from a single 5 V power supply, and all necessary bypass and decoupling capacitors are included in the package to ensure optimal performance. The ADAQ4381-4's level of system integration solves many design challenges and provides a compact, simple solution for multi-channel applications.

Conversion results can be simultaneously clocked out via a 4-wire mode for faster throughput or a 1-wire serial mode for slower throughput. the ADAQ4381-4BBCZ is compatible with 1.8 V, 2.5 V, and 3.3 V interfaces using a separate logic power supply. the ADAQ4381-4BBCZ is specified over the operating temperature range of -40°C to +105°C. The ADAQ4381-4BBCZ is designed to operate over a wide range of temperatures. The ADAQ4381-4BBCZ is specified for operation from -40°C to +105°C.

I and Q demodulation

• 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.
