HFA1135
360MHz, Low Power, Video Operational
Amplifier with Output Limiting
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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
