OPA power supply circuits ,from 34410A
as attach png file shows,,, it looks OPA power supply range extend to -4.7v -- +4.7v..... and it for no other purpose ????
ARM some registers are only word accessible...
struct {
unsigned x1: 3;
unsigned x2: 13;
} x @ 0x0x40090120; //0x40090120 ONLY WORD ACCESSIABLE
x.x2 = 2; // NOW ARM will enter hard fault handler;
so any idea to make compiler(IAR) access 0x0x40090120 ONLY base on word...
ADS2016-transistor bias uility ,help me to fix this issue.
Just try to auto gen a bias for NPN bjt under ADS2016 transistor bias uiltity tool. and got an issue as follow shows, so what's up?
(bias.ael line 344, column 5) write_datafile() failed
server error
bias.ael
:-D thank you for the explanation.. Just try to use the idea opa to simulate the same circuit ,got the same result that it works on positive feedback,,, --- TINA 9 simulator.
:bang: it looks not so easy to understand :)
thx,,, I am just curious why that positive feedback OPA still working as negative feedback in MC11 simulator.. :)
as this simple OPA internal circuit, it looks so easy to know which pin is Positive input...
MC11 is micro-cap 11, yes the positive feedback will make the OPA be saturated.
thx for your input.

many thx, Just try the TINA simulate the same circuit, but it shows diff result, positive feedback opa become saturated. :) Maybe I need to learn more about OPA...
