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.
