hello,
I have an interesting problem for you guys , I hope that you will
advice me on it.
I used the circuit diagram of the current sources given by texas
instrument. The link is given below
http://focus.ti.com/lit/ds/symlink/ina2133.pdf. If this link does not
work then go to www.ti.com and type "INA2133" in the search box and go
to its data sheet.
I used figure# 16 on page#13.
Now, the problem is that If you have two of these "voltage to current
converters" having same gorund and power supplies but input signals are
coming form different channels of the Digital to analog conveter. Now,
If one current source is outputing some charge and other one is
outputing zero charge then the current source who is outputing zero
current will act as a return path for the current source who is
outputing some current. Am I right or wrong?
Regards
john
