I wisH to connect a LISY300AL gyro to a propeller using a MCP3208 ADC. Does any know the output impedience of this gyro and wouLd it require Op Amp buffering ?
The specs do not mention the output impedience. I believe parralax is going to release a module wih this chip so you guys must know smile.gif

    I don't know, but I have that exact same setup and I just hooked it up directly. It seems to work, but I haven't done much testing with the gyros yet.

    kimh,

    An MCP3208 ADC should work fine without any buffering. Just make sure that you have a reliable power supply into the ADC and to the LISY300AL gyro. It also helps if you know what the reference voltage is to your ADC and have some way to monitor that if you are going to expect any kind of precision values that will carry any weight.
