Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The OPA2391DGKR is a dual-channel, low-power, high-speed power ratio, and low-bias current RRIO precision operational amplifier launched by (TI). It mainly has the following characteristics:

Low IQ: 24µA

Gain-bandwidth product: 1MHz

Low input bias current: 10fA

Low offset voltage: ±45µV (maximum value)

Low-temperature drift: ±1.2µV/°C

Low power supply voltage operating range: 1.7V to 5.5V

The input common-mode range exceeds the power rail by ±100mV

Fast pressure swing rate: 1V/µs

High-load capacitor drive

High output current drive: 60mA

Rail-to-rail output

Inputs where EMI and RFI have been filtered out

Small package option: VSSOP-8

The OPA2391DGKR precision amplifier device features A unique combination of high bandwidth (1MHz) and ultra-low quiescent current (24µA). These features, combined with rail-to-rail input and output, make the OPA2391DGKR an ideal choice for high-gain, low-power applications. The ultra-low input bias current of 10fA, offset voltage of only 45µV (maximum), and temperature drift of 1.2µV/°C help maintain high precision at the front end of proportional sensors and current analysis sensors with strict low power consumption requirements.

• 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.
