The HFA1105 is a high speed, low power current feedback

amplifier built with Intersil’s proprietary complementary

bipolar UHF-1 process.

This amplifier features an excellent combination of low

power dissipation (58mW) and high performance. The slew

rate, bandwidth, and low output impedance (0.08Ω) make

this amplifier a good choice for driving Flash ADCs.

Component and composite video systems also benefit from

this op amp’s excellent gain flatness, and good differential

gain and phase specifications. The HFA1105 is ideal for

interfacing to Intersil’s line of video crosspoint switches

(HA4201, HA4600, HA4314, HA4404, HA4344), to create

high performance, low power switchers and routers.

The HFA1105 is a low power, high performance upgrade for

the CLC406. For a comparable amplifier with output disable

or output limiting functions, please see the data sheets for

the HFA1145 and HFA1135 respectively.

For Military grade product, please refer to the HFA1145/883

data sheet.
