We've used REF5030A-Q1 as a 3.0V reference source for the MCU ADC, buffered by opamps. The output voltage however is incorrect, around 2.88V instead of 3.0V.
I've checked with the scope and there is no oscillation, it's pure DC 2.88V. I've seen on the forum that someone else had this problem before, no solution from TI side - what could be the issue? I've double checked the components around, I have 2x2.2uF ceramic load, and 1uF on the TRIM pin. There's almost no current drawn from the chip, only the opamp input and 20k load.
