erstes und zweites Bild. Wenn ich das richtig interpretiere, handelt es sich um eine Spannungsreferenz "AS431" im SOT-23-Gehäuse. Wenn ich mich nicht verrechnet habe, sollten sich da da 29 Volt (1+100/9,1)*2,500V als "Fußpunkt" für den Optokoppler an der "Anode" einstellen, kommt mir recht viel vor. Tatsächlich
sorgfältig gelesen. Ja, der LM334 hat eine definierte Temperaturabhängigkeit, aber auf Seite 8 "Application as a Zero Temperature Coefficent Current Source" zeigt TI den Umgang damit. Bedenken kann man anmelden, wie es mit einer anderen Diode läuft: "The recommended diode for use in this circuit is the 1N457
Temperaturkoeffizient des Stroms pro Grad muss also kleiner als 0.01% (100 ppm) sein. Das ist mit einer TL431 (typisch 50 ppm) und einem 50 ppm Widerstand zum Einstellen des Stroms gerade noch machbar. Ein LM317L dürfte das an guten Tagen schaffen, das Problem ist der Adjustment Strom, die 1.24 Volt Referenz
