Hi Ti
I develop high voltage dc.dc converter. my circuit operate very well.
but high voltage sense circuit has some problem. spec of high voltage condition(2nd output) is Vpk -7000(worst condition) , normal Vnormal -5000(general condition) ) , very stable dc(lower 100hz).
now i design lmc6001b / inverting opamp circuit + sn6501 isolation power circuit. it operate very well. but lmc6001 circuit has some nonlinears.
i use only resistor ladder 1v : -7000v --> 1k : 7M resistor ratio , inverting opamp. i want to enhance a high voltage sense circuit.
if i use lmc6001 continuously , is there any reference material to get linear characteristics of circuit(doc, reference , anything!)?
or if i change amc1301 , do i use only resistor ladder? or Ti offer other opamp?
