You will only get the DC value but for a DAC, the impedance is probably relatively flat up to at least 10kHz. It won't be quite right of course, but it will give you an indication of the overall impedance.
Forget it. Active components such as Op amps cannot be measured with a multimeter - in the worst case you may damage something with your 9 volt multimeter battery. (The impedance is a function of the feedback in the amplifier stage)
I meausred my CD player with a multimeter and the value was right at the published spec. But I have a tube output stage which may be why. It is true that opamp output impedance is feedback related but if there is some extra buffer circuit, you should be able to measure that.
