TLV8541: Oscillation Issue Caused by Input RC Filter

Tool/software:

Hi,

We are currently evaluating a circuit using the TLV8541DBVR, and have observed oscillation when an RC filter (R = 220kΩ, C = 0.01µF) is placed at the non-inverting input (+IN). Removing C30 eliminates the oscillation.

We understand that due to the TLV8541's low GBW and high-impedance design, such an RC filter at the input may degrade phase margin and induce instability. Could you please confirm if this understanding is correct?

Additionally, if there are recommended component values for input filtering with the TLV8541, your guidance would be appreciated.

Thanks,

Conor
