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.
