OPA2991QDGKRQ1 OPA2991-Q1 Automotive, Dual, 40V, 4.5MHz Low Power Operational Amplifier

Description

The OPAx991-Q1 series (OPA991-Q1, OPA2991-Q1 and OPA4991-Q1) is a family of high voltage (40V) general purpose op amps for automotive applications. These devices offer excellent DC accuracy and AC performance, including rail-to-rail input/output, low offset voltage (±125µV typical), low temperature drift (±0.3µV/°C typical), low noise (10.8nV/√Hz and 1.8µVPP) and 4.5MHz bandwidth.

With unique features such as differential and common-mode input voltage ranges on the supply rails, high output current (±75mA), high swing rate (21V/µs) and high capacitive load drive (1nF), the OPAx991-Q1 is a stable and reliable high performance op-amp for high voltage automotive applications.

The OPAx991-Q1 series op amps are available in standard packages such as SOT-23, SOIC, VSSOP and TSSOP and are rated to operate over the -40°C to 125°C temperature range.

• 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.
