Hi Sir 

We are using ADTL084ARZ ,We would like to know which OP you suggest  to replace ADTL084ARZ ? 

Temperature and SPEC need to better than ADTL084ARZ and the price need to close to TL084

    Hi Kai,

    as you are not mentioning what specification exactly should be better, I'm just throwing in the TL074 and the TL054.

    Hi Kai,

    Could you provide a little more detail? Does the amp need to have low or high supply voltage range? We will be able to get close but it is unlikely we can get you an exact match, so if you can let us know which specs are most important that would be a good starting point.

    Besides the TL074 and TL054 that Kai brought up, look at the OPA4141.

    For more precision devices, look at:
    OPA4140
    OPA4192
    OPA4197

    Best,
    Paul

    Hi Paul

    Thanks for your reply
    ADTL084ARZ is our common part ,most of project use this OP
    Due to ADTL084A is too old ,so we would like to survey new substitute to replace ADTL084A
    But I think the SPEC need to similar or better and price need to close to ADTL084A


    Application is 3 phase power meter

    Hi Kai,

    Without some further information on the circuit or the supply rails, then the devices I recommended are going to be the best ones to look at.
