HFA1130IP

HFA1130 September 1998 File Number 3369.2 850MHz, Output Limiting, Low Distortion Current Feedback Operational Amplifier The HFA1130 is a high speed wideband current feedback amplifier featuring programmable output limits. Built with Intersil’s proprietary complementary bipolar UHF-1 process, it is the fastest monolithic amplifier available from any semiconductor manufacturer. This amplifier is the ideal choice for high frequency applications requiring output limiting, especially those needing ultra fast overdrive recovery times. The output limiting 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 offers significant performance improvements over the CLC500/501/502. A variety of packages and temperature grades are available. See the ordering information below for details. For /883 product refer to the HFA1130/883 datasheet.
