This is my first post here and my background is ME so go easy on me please. I need to amplify an analog signal that is 0-5V (w/respect to ground) to be 0-24V (two wires out, not referenced to ground) to drive a solenoid coil. The problem is my power supply is + and - 12V. I have two ideas about how to do this:...
what is ME (master in electronics ?) Weird question for a master in electronics...:)
Assuming you need an analogic drive (so your solenoid acts proportional as a gas/liquid ventil or something similar) then you need a simple power amplifier.
+12V -(-12V) = 24V so you need a B (or AB) class amplifier. The solenoid must run AC coupled in situation described above, so I guess it must be a smart one. If you want two movement directions for the solenoid core, then you need a DC coupled and +24V and -24V supply with separate ground or a H bridge and +12V/-12V. The solenoid will be connected between amplifier output and the ground or between H bridge outputs.
If you need a digital drive (on or off) then you need a simple level converter from 0V to +12V (that's a NPN followed by a PNP) and solenoid will be mounted between PNP collector an -12V)
First you need to find exactly what do you want and then ask a complete and detailed question as someone mentioned.
