Hi everybody,
A few weeks ago, I spent time on this forum to find a design which allows to work with 0/10V and 4/20mA. With the help of TI employees, I found a design based on INA333.
This amplifier needs a voltage reference, so, to do that, I use a REF3230 which provides a 3V voltage reference. On my electronic board, I will have 8 amplifiers INA333, so, does I need to put 8 voltages references (one with each INA333) or only one or two are enough ?
Thank you in advance for your help,
Regards,
Fabrice Péden
