Il gallo, last version before recieving LTC6269

Ok,

I have assburger's syndrome and I have spent almost whole saturday on fixing layout.
Things I have done

  • Increased pads on opamps
  • wiring cleanup
    • compare to previous posts
  • changed 0603->0805 footprint on some components
    • 5v -> 3.3v divider
    • feedback resistors (allows more options)
  • Moved P7 feedback position where it is accessible from both sides
    • If someone like to use wired resistor as feedback resistor. Put one end on P7 and other end on input
  • Proper guard ringing resistors is hard or impossible to do with multiple resistors
    • at there is GND shield (GND is 2.5v)
I checked layout with eurocircuits pcb checker...all seems to be ok.
Expect some silkscreen problems. (text positioned bad.... and jumper silk is over pad)

Size of board is 49mm x 22.9mm

Spot silkscreen error.. no the jumper silk... the P7..

Both capacitors silkscree text...forgotted..on kicad. 

Ok... This is enough layout shit for this weekend.
