The HA-5020/883 is a wide bandwidth, high slew rate
ampliï¬er optimized for video applications and gains between
1 and 10. Manufactured on Intersilâs Reduced Feature
Complementary Bipolar DI process, this ampliï¬er uses cur-
rent mode feedback to maintain higher bandwidth at a given
gain than conventional voltage feedback ampliï¬ers. Since it
is a closed loop device, the HA-5020/883 offers better gain
accuracy and lower distortion than open loop buffers.
The HA-5020/883 features low differential gain and phase and
will drive two double terminated 75⦠coax cables to video
levels with low distortion. Adding a gain ï¬atness performance
of 0.1dB makes this ampliï¬er ideal for demanding video
applications. The bandwidth and slew rate of the HA-5020/
883 are relatively independent of closed loop gain. The
105MHz unity gain bandwidth only decreases to 77MHz at a
gain of 10. The HA-5020/883 used in place of a conventional
op amp will yield a signiï¬cant improvement in the speed
power product. To further reduce power, the HA-5020/883 has
a disable function which signiï¬cantly reduces supply current,
while forcing the output to a true high impedance state. This
allows the outputs of multiple ampliï¬ers to be wire-ORâd into
multiplexer conï¬gurations. The device also includes output
short circuit protection and output offset voltage adjustment.
The HA-5020/883 offers signiï¬cant enhancements over
competing ampliï¬ers, such as the EL2020. Improvements
include unity gain bandwidth, slew rate, video performance,
lower supply current, and superior DC speciï¬cations.
