How much external load can be connected to D/A output without a buffer?

Latest Updated:02/27/2012

Question:

How much external load impedance can be connected to D/A output pins without a buffer?

Answer:

If D/A output acceptable errors are less than 2%, the absolute accuracy of the D/A converter is a maximum of 1%. So, it is necessary to make errors due to impedance load less than 1%. Therefore, it is necessary to have resistance value of the connecting load at 99 or more times of D/A converter output resistance.
