Product Number: LTC6362

I am using LTC6362 for amplifying a signal. This is my schematic. Problem is, that it generates a 7 kHz signal and draws about 30 mA.

Hi Thimira: Remove C35. It is creating a low frequency pole in the feedback.

Hi Glen, Thank you so much. This actually worked. Now there is no excess current and I don't see the 7kHz signal.
