TPS62130 Capacitor between AVIN-AGND

Other Parts Discussed in Thread: TPS62130, TPS62140

Hi

I have a question for a capacitor between AVIN and AGND.

On TPS62130AEVM, there is a capacitor between AVIN-AGND(C7),

However there is no capacitor between AVIN-AGND on TPS62140AEVM.

What is this capacitor for?
