TLV9004: Layout of feedback resistor and feedback capacitor

Hi,

both should sit close to the amplifier

I personally mount the feedback capacitor closest to the OPAmp.

Increasing the distance will add unwanted stray impedances and form hum loops. Especially the -input of OPAmp is vulnerable. Don't allow too long copper traces at the -input but have all components mounted closest to the -input. Also, add an isolation resistor at the output to isolate capacitive loads.
