HFA1245
Dual, 420MHz, Low Power, Video, Current
Feedback Operational Amplifier with
Disable
The HFA1245 is a dual, high speed, low power current
feedback amplifier built with Intersil’s proprietary
complementary bipolar UHF-1 process.
The HFA1245 features individual TTL/CMOS compatible
disable controls. When pulled low they disable the
corresponding amplifier, which reduces the supply current
and forces the output into a high impedance state. This
feature 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 HFA1245
useful as the A/D driver/multiplexer.
The HFA1245 is a low power, high performance upgrade for
the popular Intersil HA5022. For a dual amplifier without
disable, in a standard 8 lead pinout, please see the HFA1205
data sheet.
