I would like to use LT1991 as a differential amplifier with Gain of 0.4
My supply voltages are +12VDC and -12VDC
Input = differential voltage signal of 42V max. (i.e., +21V to -21V w.r.t. GND or 0 to 42V w.r.t. GND or -42V to 0V w.r.t. GND)
I am trying to use LT1991 Online Design Tool - Beta Version
And configured as follows:
And from the highlighted text what i understand is my signal range at the differential inputs cannot exceed +12V and -12V.
But as per requirement [ differential voltage signal of 42V max. (i.e., +21V to -21V w.r.t. GND or 0 to 42V w.r.t. GND or -42V to 0V w.r.t. GND)]
Will this configuration support my requirement ?
or
is there any other topology which I need to try implementing ?
