... Intersil (and design registered trademark of Intersil Americas Inc. Copyright © Intersil Americas Inc. 2002. All Rights Reserved Description The HFA-0005 is an all bipolar op amp featuring high slew rate (420V/µs), and high unity gain bandwidth (300MHz). These features combined with fast settling time (20ns) make this product very useful in high speed data acquisition systems as well as RF, video, and pulse amplifier designs ...

... Figure 30. Note that there will be a 6dB loss from input to output. The HFA-0005 has an integral 50Ω ±20% resistor connected to the op amp’s output with the other end of the resistor pinned out. This 50Ω resistor can be used as the series resistor instead of an external resistor ...

... HFA-0005 Saturation Recovery V+ C When an op amp is over driven output devices can saturate and sometimes take a long time to recover. By clamping the input to safe levels, output saturation can be avoided. If out- R put saturation cannot be avoided, the recovery time from C 25% overdrive is 20ns and 30ns from 50% overdrive. ...
