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
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
