I need to use an ISO124P isolation amplifier. The data sheet for the device is here http://www.ti.com/lit/ds/symlink/iso124.pdf
My question is with regards to powering the amplifier. I am really confused with the power supplies. I think I need two different power supplies.
In my opinion I should connect:
- Ground1 to Gnd1
- +Vcc1 to Vs1
- -Vcc1 to -Vs1
- Ground 2 to Gnd 2
- +Vcc2 to Vs2
- -Vcc2 to -Vs2
I am correct? Or should I use the diagram of the Figure 22 or Figure 23 of the data sheet for powering the ISO amplifier?
I know this is probably stupid, but I'm pretty new to this stuff.
Any help would be appreciated.
Thanks so much.
