OPA694: OPA694

Part Number: OPA694

Dear TI team:

    My customer used OPA694 for signal amplification. The previous power supply is ±5V, the output is normal, and when they change power to +3.3V and -5V, the output level is lower than before, why is it happen?

   And if customer used +4V and -5V, can OPA694 output normal? 

   What data are required from customers? The customer is not very willing to provide some information, the input is changing, is pulse.
