Part Number: OPA991

Hello,

I need to identify replacement op amps for the AD711, AD8627 and ADA4000-1 from ADI. What are the best P2P(Pin to Pin) replacement amplifiers from TI? Is OPA991 the best one for it?

Thanks!

  • Hi Katherine,

    You can look at our newest high voltage op amp OPA991, which is a 4.5MHz, single channel, low Vos and low noise amplifier. It’s RRIO and the slew rate is 21V/us.

     Here is a table showing the performance differences among AD711, AD8627 and ADA4000-1, and the recommended device.

    Thank you,

    Tim Claycomb
