REF5025: output only 2.2V~2.3V following basic connections
I want to used ref5025 and OPA735 for my ADC circuit to get +2.5V and -2.5V for the voltage reference. But I found the current of the circuit is too big. the total current of power supply is 15mA, and the power consumption is 51mw in no load，can you give me some advice to design the circuit？
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

This is something to ask the amplifier team, but just based on comparing quiescent current, the OPA187 will save you power consumption. We also have a new generation series reference that has better drift for significantly lower power called the REF3425. I would suggest changing to two of these devices for lower power consumption.
