hi
im planning on using this current transducer to monitor current on a project, can i just use the output from it (2.5 to 4.5v) without any other circuitry straight into an analog input?
thank you

in the speck sheet it quotes Rl  (load resistance) should be greater than 2k should there be a 2k resistor to ground?

Yes.

No.  The input impedance of the Arduino is >2K so you should be able to connect the output directly to it.  Just hook "5V" to +5V, "0V" to Ground, and "OUT" to an analog input pin.
