Data Sheet September 1998 File Number 3955.3

330MHz, Low Power, Current Feedback Video Operational Ampliﬁer with Output Disable

The HFA1145 is a high speed, low power current feedback ampliﬁer built with Intersil’s proprietary complementary bipolar UHF-1 process.

This ampliﬁer features a TTL/CMOS compatible disable control, pin 8, which when pulled low reduces the supply current and forces the output into a high impedance state. This allows easy implementation of simple, low power video switching and routing systems. Component and composite video systems also beneﬁt from this op amp’s excellent gain ﬂatness, and good differential gain and phase speciﬁcations.

Multiplexed A/D applications will also ﬁnd the HFA1145 useful as the A/D driver/multiplexer.

The HFA1145 is a low power, high performance upgrade for the CLC410.

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