Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AD7175-2BRUZ is a low-noise, fast-build, multiplexed, 2/4-channel (fully differential/pseudo-differential) sigma-delta analogue-to-digital converter (ADC) for low-bandwidth inputs. The device has a maximum channel scan rate of 50 kSPS (20 µs) for fully established data. The device's output data rates range from 5 SPS to 250 kSPS.

The device is powered by 5 V AVDD1 or ?2.5 V AVDD1/AVSS and 2 V to 5 V AVDD2 and IOVDD supplies.The AD7175-2BRUZ is rated over the -40°C to +105°C operating temperature range and is available in a 24-pin TSSOP package.

Chromatography

• 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?
