Hello group --
A virgin poster here.
I am looking for a rugged, fully packaged operational amplifier that can be installed under the hood of a car. The temperature ranges, noise, etc. might make this a challenging environment.
The component that I am looking for is simple. Input voltage 0-5v. Output voltage 0-5v. Hopefully, input and output voltage should be close to the same, but I don't need huge precision. Then the ground connector and a connector to the car's main electric circuit that runs the power windows and whatnot. So I am looking for four wires altogether.
Here's more about the application. The input 0-5v comes from a MAF signal. The output is going to the fuel pump control signal, 0-5v. I don't know how much current it draws, but probably not much -- it's just a signal for the pump controller, and it doesn't drive the pump itself. Because I have not been able to find out much detail about how the pump behaves and because MAF signal is used for many other important things, I don't want to screw with the MAF signal too much and was thinking about putting an opamp between. But now I need a component that can survive inside a car (hot, cold, wet, vibrations, interference, etc.) If what I am trying to do here makes no sense, please, please let me know before go further with this project.
Anyone know a good component to use?
Thanks in advance for your help!
Best,
Tuomo
