Part Number: OPA2180
Other Parts Discussed in Thread: OPA2205, OPA2188

Hi team,

Could you suggest a solution to replace OP2177? same or better spec and pricing under $1.

I use cross reference. the result is below.

If OPA2180 is okay. Do you have a comparison table? Thanks

    Hi Jimmy 

    The OPA2205ADR is a higher performance device when compared to the OP2177. It is also a bipolar op amp (just like the OP2177). The OPA2180 is a CMOS, zero drift which has quite a few differences. Please see the quick comparison below. 

    Can you share the volumes and the application?
