The HFA1135 is a high speed, low power current feedback
amplifier build with Intersil’s proprietary complementary
bipolar UHF-1 process. This amplifier features user
programmable output limiting, via the VH and VL pins.
The HFA1135 is the ideal choice for high speed, low power
applications requiring output limiting (e.g. flash A/D drivers),
especially those requiring fast overdrive recovery times. The
limiting function allows the designer to set the maximum and
minimum output levels to protect downstream stages from
damage or input saturation. The sub-nanosecond overdrive
recovery time ensures a quick return to linear operation
following an overdrive condition.
Component and composite video systems also benefit from
this operational amplifier’s performance, as indicated by the
gain flatness, and differential gain and phase specifications.
The HFA1135 is a low power, high performance upgrade for
the CLC501 and CLC502.
