    Taito,

    Please see replacement parts below:

    OPA2377 -> OPA2397, TLV2397, OPA2325

    OPA2376 -> OPA2392 or OPA2387

    OPA2188 -> OPA2182 or OPA2187

    1. Not a grade out. OPA2377 is an untrimmed version of OPA2376.

    2. Yes.  OPA2188 is a high grade of OPA2180.

    Hi Taito,

    OPA2376 is trimmed means that its input offset voltage and drift is adjusted in the package by blowing resistor links.

    Grade out means that in the final test the parts are sorted out by parametric limits. For example, parts with |Vos|<25uV go to OPA188 bin while parts with 25uV<|Vos|<75uV go to OPA180 bin (see below).
