DRV3245E-Q1: Low pass filter on current sensor outputs SOx

Part Number: DRV3245E-Q1

Hello TI Expert,

From charpter 7.3 Recommended Operating Conditions in datasheet of DRV3245E-Q1, we can see that the maximum external capacitive load on shunt amplifier output (without external resistor) is 60pF.

But we got a requirement that Capacitor value needs to be increased and Resistor value needs to be decreased.

So I want to know what's the reason for 60pF limitation?

Is there any mathematical relationship when we choose R and C when external resistor is considered? For example, if C=220pF, R>=? If C=1nF, R>=?

Thanks in advance.
