I am using LM6172 Dual High Speed, Low Power, Low Distortion, Voltage Feedback Amplifiers in voltage follower mode. In the datasheet typical value for closed loop output impedance is given as .01 ohms at 10Khz, Can someone help me in providing the information about worst case output impedance closed loop can I get from LM6172(maximum output impedance) or how can I calculate it.
Thanks
