HFA1130IBZ中文资料INTERSIL数据手册PDF规格书

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.
