dalje, za RTD, ovaj filter od R25, R26, C9 i C10 je UZASNO SPOR ... ja sam jos originalno C10 bio stavio 10uF to traje pola sada da krene da radi ... tako da te vrednosti valja preracunati .. ima ovde experata za te low pass filtere pa si preracunajte tu neku idealnu vrednost ... ako imate problem generalno skinede C10 i sve radi super Big Grin, meni je ako se dobro secam na mojih par komada C9 10nF a C10 100nF

Prekontrolisacu ja malo taj filter nije problem.

Nego, sta radi ovaj C11 na izlazu iz OP?
Tu nebi trebao da bude nikakav kondenzator a ako si hteo sa njim nesto da dodatno filtriras, MORA da se stavi "izolacioni" otpronik sa izlaza iz OP (7 nozica) od nekoliko stotina ohm.
Mozda ti je radilo ali to je NO-NO za OP, tezak kapacitivni load …

Evo gledam DS za MCP619, navode specifikaciju za svega 60pF opterecenje (Cl), ajd da kazemo da je 100pF krajnja granica, ali 10nF je previse.
