Describe
Low bias current, precision (dual channel) operational amplifier

Product Description

OP297GSZ7 is a dual-channel operational amplifier that integrates precision performance into a space-saving industrial-standard 8-pin SO package, combining precision performance with low power consumption and ultra-low input bias current, making it suitable for a wide range of applications.


The OP297GSZ7's precision performance includes extremely low offset (less than 50 µV) and low drift (less than 0.6 µV/°C). The open-loop gain exceeds 2000 V/mV, ensuring high linearity in any application. The common-mode rejection ratio exceeds 120 dB, effectively eliminating errors caused by common-mode signals. The power supply rejection ratio exceeds 120 dB, minimising offset voltage variations in battery-powered systems. Additionally, each amplifier draws less than 625 µA of supply current and can operate with supply voltages as low as ±2 V.


The OP297GSZ7 maintains picoamp-level bias current across all temperatures using a super-beta input stage with bias current cancellation. This contrasts with FET-input operational amplifiers. FET-input operational amplifiers have bias currents in the picoampere range at 25°C, but the bias current doubles for every 10°C increase in temperature; when the temperature exceeds 85°C, the bias current reaches the microampere range. The OP297GSZ7 has an input bias current of less than 100 pA at 25°C and remains below 450 pA across the entire military temperature range.

FAQ

  • 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.
