  • RE: LM321: Does TI have a rail-to-rail OPAMP that P2P with LM321?

    Resolved
    CK Ho, TLV2370, OPA743 and OPA191 are few options with high voltage (>12V) supply capability, comparable specs and RRIO. But these are not directly P2P compatible with LM321. You will have to swap your Pin1, Pin3 and Pin 4. Lets us know if this is…
