Hi!
Need help in assessing the correctness of the layout of the circuit. All parts were calculated according to datasheet.

Hello Ruslan,

In reviewing your schematic and layout I would do the following:

1. Place decoupling capacitor next to pin 7 & 8
2. Add a 10nF differential capacitor between IN- & IN+

Hi, Leon.
Thanks for replying. I corrected my layout according your advices. Bypass cap is near pin 7,8; added 10nF cap between In- & in+.
Is it better than previous one?
