HFA1245/883
Dual, High Speed, Low Power, Video
Operational Amplifier with Output Disable
Description
The HFA1245/883 is a dual high speed, low power current
feedback amplifier built with Harris’ proprietary complementary bipolar UHF-1 process.
This amplifier features individual TTL/CMOS compatible disable controls, which when pulled low, reduce the supply current and force 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 HFA1245/883
useful as the A/D driver/multiplexer.
The HFA1245/883 is a low power , high performance upgrade
for the popular HA5022/883.
