PGA280: Output Loading

Part Number: PGA280
Other Parts Discussed in Thread: PGA281,

Good day,

In a lot of the reference designs that utilize the PGA280/281 (Including the SBOM817 TINA File for PGA281), I see some light load resistors added to the PGA Output (2.5K in the case of SBOM817).

Is this beneficial in any way?  Does the PGA280 need a little load to drive against when connected directly to a Delta-Sigma ADC?

We're working on a design where every square millimeter matters, so I'm trying to avoid placing parts for no reason.

Thank You,
