HFA1130
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.
