HA-5020

100MHz Current Feedback

Video Amplifier With Disable

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.
