Can I use ISO122 with +Vs = 15V and -Vs = 0V/GND, for both sides input and Output. And if we can then is it possible to have Input voltage range upto 12.5V with these supplies?
Nilesh,
A negative power supply is required on both input and output to handle input/output signals down to 0V. For signals ranging from 0V to 12.5V, I recommend a power supply of -5V and +18V on both input and output sides.
Without negative supplies on input and output the lower end of the signal range would be approximately 3V.
