Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADS7057IRUGR is a 14-bit 2.5 MSPS SAR ADC that supports fully differential inputs in the ±AVDD range from 2.35V to 3.6V.

Internal offset voltage calibration maintains excellent offset voltage specifications over the full AVDD and operating temperature range.

The device supports an SPI-compatible serial interface controlled by CS and SCLK signals. The input signal is sampled by the falling edge of CS, while SCLK is used for conversion and serial data output. The device supports a wide digital supply range (1.65V to 3.6V) for direct connection to a variety of host controllers, and the nominal DVDD range of the ADS7057 (1.65V to 1.95V) is compliant with the JESD8-7A standard.

The ADS7057IRUGR is available in a small 8-pin X2QFN package for operation over a wide range of industrial temperatures (-40°C to +125°C). The device's small size and extremely low power consumption make it ideal for space-constrained, battery-powered applications requiring high-speed, high-resolution data acquisition.

• 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.
