Part Number: OPA1612

Hi sir 

Have any performance different between I use +/-15V and +/-5V to supply OPA1612 ?

Which one have better performance??

Thanks

    Hi Kai,

    I don't believe you'll see any significant difference in performance at ±5V supplies vs. ±15V supplies. Of course, if your application requires output swings close to ±5V, you will see increased distortion with the lower supply voltage. Additionally, the common mode range for the OPA1612 with ±5V supplies would be about ±3V, which would limit your available input range for a noninverting configuration (particularly for a noninverting gain of 1).
