LMP91000: Does it require a unit gain buffer from Vout to ADC.

Herve Grabas50

Part Number: LMP91000

Does the LMP91000 require a unit gain buffer between Vout and the ADC? I have seen design with or without a buffer.
What are the risks of not using a buffer.

If yes what are the recommended specs for the buffer?

Offset
Input current
Bandwidth
Noise

Thanks!
