HFA1135

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

OVERVIEW

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.
