Hi Everyone,
This is what I have:
Single supply +48V - Can't be changed.
LM2575HV-3.3 that brings down the 48V to 3.3V
Mcu running at 3.3V
Low pass filter to smooth down PWM to 0-3.3V analog signal.
This is what I need:
OP Amp with gain of 3 to give me a 0-10V signal.
I used LM358 in the past when my supply was +12V without problems, but It can't be used due to the +48V of the current supply.
I've seen quite a few that work on +/-30V, such as OPA551. My question is if I have single supply of +48V instead of dual +/-30V, is it safe to use?? Or I need to find something that would work +/-48V??
Thank you,
RI
