I think that you should take the capacitor that you marked with a cross (is that C21?) and make sure that on the left side it's not connected to GND, but rather to the - (aka INN, below) input signal coming from the board. You have a few options to achieve that:
- cut the ground island that it's connected to and solder a wire to its left pad , see image (purple is cut, red is wire)
- cut the ground island up to and including IN-, excluding any via as per the image below. Also cut around the - input pad on the other side so that it's not connected to ground on either side. Always double check with a multimeter that it's not connected. Then you can use the existing
- input pad for INN.
- remove it and place it vertically on its right pad, then solder the
INN wire to its left side, which is now sitting elevated above the PCB
- remove it and solder a THT capacitor of the same value instead of it, with one side on the right pad of C21 and the other side connected to the
INN wire
