    ... Conversely, the LME49713 current feedback amplifier features a small-signal bandwidth that is relatively independent of the closed-loop gain. This is shown in Figure 1 where the LME49713’s gain is –1,–2, –5 and –10. Like all current feedback amplifiers, the LME49713’s closed-loop bandwidth is a function of the feed- back resistance value ...
