Hi Team,
We were planning to use OPA604AU op-amp with Ground referenced V+ (40V ) supply.
Can you please suggest me How to handle Offset trim pins of this Op-amp.

Hi D.Meenalochini,
Can you please suggest me How to handle Offset trim pins of this Op-amp.
If you want to trim and adjust and OPA604's voltage offset, you may use 100kΩ potentiometer and configure the trim circuit as shown in Figure 1. You have approx. +/-50mV trim range as stated.
Or you may leave the OPA604 offset trim pins floating if you don't intent to use the offset adjust function.
If you have additional questions, please let me know.
Best,

Meenalochini,
It makes no difference whether you power OPA604 with dual or single supply voltage - the offset trim potentiometer must be connected between the pins 1 and 5 with middle terminal tied to negative rail - see below.
