Default what's the output impedance of a LM6171?

From the data sheet, the open loop output impedance is around 15ohm.

However, how does this change when the LM6171 is use as a simple inverting amplifier with a 1K2 feedback resistor?

(Used after the DAC current output to do the I/V conversion and amplify the voltage.)

Thanks

for practical purposes 0 ohm as long as you don't try to draw too much current.......

Talking thanks

As I am designing a passive filter after the opamp, can I assume the output impedance is zero? Because the filter compoments' values do depends on this output impedance.
