Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADS131M08QPBSRQ1 is an eight-channel, synchronous sampling, 24-bit Delta-Sigma analog-to-digital converter (ADC). The ADC has wide dynamic range, low power consumption and specific characteristics of power measurement. With these characteristics, the device is well suited for power metering, power metering and circuit breaker applications. The ADC input can be connected directly to a resistive voltage divider network or a power transformer to measure voltage, or to a current transformer or Rogowski coil to measure current. Individual ADC channels can be configured independently based on sensor input. Low noise, programmable gain amplifiers (PGA) provide gains from 1 to 128 to amplify low level signals. The device integrates interchannel phase calibration and offset and gain calibration registers to help eliminate signal chain errors.

The ADS131M08QPBSRQ1 integrates a low drift, 1.2V reference, thereby reducing the area of the printed circuit board (PCB). The cyclic redundancy check (CRC) option can be enabled separately in data input, data output, and register mapping to ensure communication integrity. Devices comply with AEC-Q100 certification for automotive 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.
