OPA4350: Drop in replacement for OPA4350.

Part Number: OPA4350
Other Parts Discussed in Thread: OPA828, OPA4192, OPA4376, OPA4388

Hi, I was wondering if there is a newer component to update OPA4350EA/250 OPAMP? A replacement component that has better characteristics.

Thank you.

    What characteristics are important to you?  OPA828 (single), OPA4320 and OPA4365 (quad) have better dc specs but cannot drive uF's of capacitive load as OPA4350 is able to do.

    Thank you, Marek, for your reply. I was tasked to look at one of our older designs and see if components can be updated with more up to date parts. This is a test and measuremet device and I am interested in improving OPAMP DC error parameters (Input bias current, Input offset voltage, Noise figure). We do not want to change the PCB, so I am hoping to find drop in replacement part.

    If the bandwidth is not the most critical, please take a look at OPA4376 (max supply of 5.5V) and OPA4192 (max supply of 36V). We will also soon introduce OPA4388 with max Vos of 5uV but the closest in speed to OPA4350 but with much better precision would be OPA828 (no quad).
