    Need help on converting 0-5v signal to 0-10v signal

    I'm not sure what you mean by saying I am not using it in a rail-to-rail setting? The op-amp has ground and +15 volts, and it mentions that it can go up to within 2 volts of the supply voltage. I am using it to output between 0-10 volts. I could probably update the design and use a regulator...

    Need help on converting 0-5v signal to 0-10v signal

    Is it possible that the "analog output" is pulling too much current? This opa171 is rated at 25mA max output current... is this a failure that would be associated with that?

    Need help on converting 0-5v signal to 0-10v signal

    Here is an updated schematic by the way: The resistor in front of the Zener diode is just a 10 ohm 1/6 watt resistor. The 15V zener can dissipate 1 watt, the part number for that is "ZM4744A-GS08". Not gonna lie, I had a bit of a hard time trying to figure out the proper combination of zener...

    Need help on converting 0-5v signal to 0-10v signal

    Hey guys, first off I want to say thanks for all of the help so far! (This thread has been stale for a while). So I ended up going with a rail-to-rail op amp (OPA171AIDR) and for the most part it has been working great. I provide it a 0-5 volt signal and it outputs 0-10 volts. I am supplying it...

    Need help on converting 0-5v signal to 0-10v signal

    I will try that out. Quick question though... can I toss in a 14 volt or 15 volt zener diode to protect the power input at least?

    Need help on converting 0-5v signal to 0-10v signal

    My circuit is in my original first post. As far as the output current... unfortunately that is part of the problem... I am using this circuit to control an external circuit (replaces a manual control) and I am not sure what the current draw is.... though I might be able to measure it. It should...

    Need help on converting 0-5v signal to 0-10v signal

    Well, I decided to go with the LMC6081, it generates a nice 0-10 volt signal...... but sure enough it cooks quickly when its operating on the circuit board. It fails either by making a short from the power to the output, or it fails bu only outputing a small amount. So it looks like I need to...

    Need help on converting 0-5v signal to 0-10v signal

    Thanks for the responses! So its recommended I go with the OPA341, or an LM324? I also had someone recommend using a LMC6081. How do I decide which one to go with? They all look like good options.... though the LM324 has 4 chanels on it, which I only need 1.

    Need help on converting 0-5v signal to 0-10v signal

    Hi guys, I am currently using a parallax propeller micro controller to generate a signal. I am using a ADC to create a 0-5v signal, and an op-amp to convert this into a 0-10v signal. I am experiencing a problem with it. Everything works fine until I go below 1.9v on the input of the op amp... at...
