HFA1130 FN3369
Rev 5.00
April 25, 2013 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. Features User Programmable Output Voltage Limits Low Distortion (30MHz, HD2) -56dBc -3dB Bandwidth 850MHz 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. Very Fast Slew Rate 2300V/Вµs Fast Settling Time (0.1%) 11ns Excellent Gain Flatness
