Re: current output DAC's

Hi,

I noticed some DAC's are current output instead of voltage output,
what is the practical difference when using these in a circuit and
in what situations would it be better to use a current output DAC?

cheers,
Jamie

In Instrumentation applications 1 to 5 milliamp and 4 to 20 milliamp
signals are used to transmit over long distances to eliminate
attenuation caused by line resistance. Hence in any situation in
which you want to make sure the amplitude of the signal at the
receiver is the same as the amplitude of the signal at the transmitter
a current signal is preferred over a voltage signal.
