Description

The HFA1130/883 is a high speed, wideband current feedback amplifier featuring programmable output clamps. Built with Intersil' proprietary complementary bipolar UHF-1 process, it is the fastest monolithic amplifier available from any semiconductor manufacturer.

This HFA1130/883 amplifier is the ideal choice for high frequency applications requiring output limiting, especially those needing ultra fast overdrive recovery times. The output clamp function allows the designer to set the maximum positive and negative output levels, thereby protecting later stages from damage or input saturation. The sub-nanosecond overdrive recovery time quickly returns the amplifier to linear operation following an overdrive condition.

The HFA1130/883's wide bandwidth, fast settling characteristic, and low output impedance, coupled with the output clamping ability, make this amplifier ideal for driving fast A/D converters.

Component and composite video systems will also benefit from this HFA1130/883 amplifier's performance, as indicated by the excellent gain flatness, and 0.03%/0.05 Degree Differential Gain/ Phase specifications (RL = 75Ω).
