Other Parts Discussed in Thread: OPA2197, OPA1602, OPA1612, OPA1652, OPA1688
Hi Team,
I'm looking for a replacement for the AD712 that is available in the standard SOIC-8 package. Non rail-to-rail input is preferred as my customer does not want the distortion due to the nonlinear transition region of the P&N input differential pairs when the op amp common mode input voltage varies. My customer had chosen ADA4610-2 on their board, but saw the distortion and as a result, tried the OPA2197, which has better results, but they are still seeing some distortion. All of the distortion they are seeing is caused by the op amp's rail-to-rail input architecture. They want something with specifications better or at least as good as the AD712.
- not rail-to-rail input
- doesn't have to be RRO
- +/- 15V supply
- common mode up to 13V
- no phase reversal on input
- 5-20MHz unity gain BW
Do we have anything that would improve on the distortion they are seeing with our OPAx197 devices?
Thanks in advance for your support.
Best Regards,
Brian Gosselin
