Hi all
got a question for the electronics experts
I have a 3.5 bar map sensor,
and I want send the signal (0-5vdc) to 2 devices (one is my wideband display/datalogger, and the other is the AEM ecu)
I don't want to reduce the voltage/current by tapping another device into it. Is there a signal amplifier that can split the signal while maintaining the correct voltage of the original???

Someone mention an Opamp? but there are so many and I wouldn't know how to pick the right one

thanks

Chances are the input impedance of the devices are high enough that it will not drop the voltage coming from the sensor. Have you tried connecting both devices yet?

I'm gonna give it a try soon
stil need to sort out some issues with engine before install the aem
