Hi,
Ok I'm a newbie to op amp circuits, but I want to make an differential op amp for improving control of a cylinder (hyd) that is connected to a linear transducer with an output of (0 to 10V).
Currenlty I'm donig the close loop in the PLC even with a low scan rate of 3ms obviously is still not fast enough.
So I thought why not use a differential op amp and let the op amp do the close loop control based on the transducer position (0-10V) and the command signal (0-10V)
Now I have read a lot articles about this and viewed many circuits and also have seen chips (dip) that have all of the resistors and everything already in the chip such as the TI INA111
The analog output signal of the command is is at 75mA and 250mA of the linear transducer.
Oh ya one more thing I would to use a dual output DC_DC Converter to supply the op amp with the +15 & -15V from a 24v soruce.
Any suggestions from the experts here?
Thanks,
Deke
