Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADS1219IRTET is a 24-bit precision analogue-to-digital converter (ADC) that integrates all the features required to implement common system monitoring functions such as supply voltage, current and temperature monitoring. The device implements two differential inputs or four single-ended inputs through flexible input multiplexers (MUX), rail-to-rail input buffers, programmable gain stages, voltage references and oscillators.

The devices are equipped with buffers for direct connection to high impedance sources. The buffer can be supplied with a gain stage with selectable gains of 1 and 4. The ADS1219IRTET performs conversions at data rates up to 1000 samples per second (SPS) with single-cycle stability. For industrial applications in noisy environments, the digital filter provides both 50Hz and 60Hz suppression when sampling at 20SPS.

The ADS1219IRTET has an I2C-compatible 2-wire interface that supports I2C bus speeds up to 1Mbps. Sixteen different I2C addresses can be selected for the device via two address pins.

• 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.
