REF5030AQDRQ1 is an automotive-grade (AEC-Q100 certified), low-noise, ultra-low temperature drift, high-precision 3V series voltage reference chip, in an 8-SOIC package, suitable for precision voltage reference applications in harsh environments.

REF5030AQDRQ1 Core Features

High precision voltage output

Fixed 3V output, initial accuracy ± 0. 1%, ensures a stable and reliable reference voltage.

Ultra-low temperature drift coefficient: 8ppm/°C (standard grade), suitable for wide temperature environment.

Low noise performance

The noise in the frequency band of 0.1 Hz ~ 10Hz is only 9 µ V < sub > p-p </sub >, which is suitable for high-precision data acquisition system.

Wide input voltage range (3.2 V ~ 18V)

It adapts to a variety of power environments, and supports ± 10 mA output/draw current, with strong driving ability.

Automotive-grade reliability (AEC-Q100 certified)

The operating temperature range is-40 °C ~ 125 °C, which meets the stringent standards of automotive electronics.

Low quiescent current (1.2 mA)

Optimized power consumption for battery-powered or low-power 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.
