6.4 Source Inductance

Like any high frequency buffer, the LMH6321 can oscillate with high values of source inductance. The worst case condition occurs with no input resistor, and a purely capacitive load of 50 pF, where up to 100 nH of source inductance can be tolerated. With a 50 Ω load, this goes up to 200 nH. However, a 100 Ω resistor placed in series with the buffer input will ensure stability with a source inductances up to 400 nH with any load.
