Part Number: OPA376


Please check and inform can we use OP-Amp part no: OPA376AIDCKR  by connecting +3.3V and -2.1V as working voltage as in specification, it was mentioned as 2.2-5.5V or ±1.1-2.75V.

    That total is 5.4V, under the 5.5V max. So sure, if the supply tolerances are ok.

    Hi Deepthi, 

    As Michael indicated, the delta voltage from the supply rails are within 5.5Vdc, so it complies with the OPA376 recommended operating conditions. Please make sure that 3.3Vdc and -2.1Vdc are properly decoupled and stiff voltage sources, and does not change the compliance voltage readily with a current load (regular LDOs should suffice). 

    If you have additional questions, please let us know. 

    Best,

    Raymond
