about the noise density of voltage reference IC.

Hello,

I'm looking for low-cost,low-noise voltage reference IC for precision ADC.

ADR391/381/361 are matched for my purpose.

So,I'd like to know the value of noise density at 100KHz.

I can see this value only on datasheet of ADR391,however up to 10KHz.
pls refer to the chart.

Do you have the value(at 100KHz) of these three IC's?.

It would be greatly appreciated if advice could be gotten.

Best Regards,
Kou
