The HA-5020 is a wide bandwidth, high slew rate amplifier
optimized for video applications and gains between 1
and 10. Manufactured on Intersil’s Reduced Feature
Complementary Bipolar DI process, this amplifier uses
current mode feedback to maintain higher bandwidth at a
given gain than conventional voltage feedback amplifiers.
Since it is a closed loop device, the HA-5020 offers better
gain accuracy and lower distortion than open loop buffers.
The HA-5020 features low differential gain and phase and
will drive two double terminated 75 coax cables to video
levels with low distortion. Adding a gain flatness
performance of 0.1dB makes this amplifier ideal for
demanding video applications. The bandwidth and slew rate
of the HA-5020 are relatively independent of closed loop
gain. The 100MHz unity gain bandwidth only decreases to
60MHz at a gain of 10. The HA-5020 used in place of a
conventional op amp will yield a significant improvement in
the speed power product. To further reduce power, HA-5020
has a disable function which significantly reduces supply
current, while forcing the output to a true high impedance
state. This allows the outputs of multiple amplifiers to be
wire-OR’d into multiplexer configurations. The device also
includes output short circuit protection and output offset
voltage adjustment.For multi channel versions of the
HA-5020 see the HA5022 dual with disable, HA5023 dual,
HA5013 triple and HA5024 quad with disable op amp data
sheets.
