Hello
are there Low-Voltage, Low Ib, RR Single OpAmps with Class-AB output stage similar to OPA202 ?
Do you have LTspice model for such a type?
Thanks in advance for your help.

Hi DaADev,
I think LTC6081/LTC6082 or LTC6078/LTC6079 may be very close to OPA202 that you asked about. But they are duals and quads (not single like OPA202).
All of these have the LTspice model readily available from within LTspice program.

Dear Hooman,
the OpAmps you suggested don't have bipolar output stage.
What i asked for is one equipped with bipolar class AB output stage. Pls have a look at the OPA202/2202 Datasheet where a inner circuit is shown. Or have a look even at LM108 or 741 Opamps which also have bipolar class AB output stage.
I still hope ADI has such OpAmps. Input Bias Current is less important. Board Space is an important constraint.
Best Regards
Achim
Hi Achim: most of the LTC opamps had simplified schematics in the data sheet. Check out LT1351 family, or LT1012 (low Ibias) or LT1007 or LT1028. Are those the kind of output stage you're looking for?
