Evo malo i oscilograma.Žice do kondezatora i pota su malo duže jer tako će biti i u kutiji pa da znam šta me čeka da ne bude posle iznenađenja.

Sa Ct 2n2 je išao do 13kHz.Nisam probao 1n jer nemam MKP verziju.Može tu još da se smanji R6 na 2k2.Sad sad na poslu probaću sutra dokle ide mada Macola kaže:
"Sa tom najboljom izvedbom, tj. sa 4 x op-amp OPA4192, sprava će izuzetno linearno i precizno raditi i na gornjem opsegu frekvencija koji su iznad 10KHz i čak do preko 200KHz.

To ne mogu raditi op-amps sa slew rate ispod 15V/uS."

Ok, meni treba konkretno samo trougao zbog nekih drugih stvari cistoca signala i nije toliko kriticna , bitno je da moze da dodje do 200kHz , nego ja kod tebe vidim dve plocice a na jednoj plocici vidim samo 555, sta ima na drugoj...

Ok, pravicu ga sigurno ali ce biti integrisan na neki drugi uredjaj za testiranja tako da mi ta plocica trenutno ne vrsi ulogu u svakom slucaju hvala, interesuje me koji si ti op amp stavio ne vidi se jasno na slici...
