Why use a tantalum instead of a ceramic capacitor?
On page 72 of the AD7124-4 datasheet it says:
Decouple AVDD with a 1 μF tantalum capacitor in parallel with a 0.1 μF capacitor to AVSS on each pin.
Why would this capacitor be specified to be a ...

MLCC vs Tantalum: For Decoupling, input to regulator and ripple reduction
I require a 3.3uf capacitor in a 30 VDC environment for three different purposes:
decoupling of precision ADC or DAC;
input to a regulator (linear, switching, LDO); and
output of any regulator for ...
