100MHz Current Feedback Amplifier
The HA-5004 current feedback amplifier is a video/wideband
amplifier optimized for low gain applications. The design is
based on current-mode feedback which allows the amplifier
to achieve higher closed loop bandwidth than voltage-mode
feedback operational amplifiers. Since feedback is
employed, the HA-5004 can offer better gain accuracy and
lower distortion than open loop buffers. Unlike conventional
op amps, the bandwidth and rise time of the HA-5004 are
nearly independent of closed loop gain. The 100MHz
bandwidth at unity gain reduces to only 65MHz at a gain of
10. The HA-5004 may be used in place of a conventional op
amp with a significant improvement in speed power product.
Several features have been designed in for added value. A
thermal overload feature protects the part against excessive
junction temperature by shutting down the output. If this
feature is not needed, it can be inhibited via a TTL input
(TOI). A TTL chip enable/disable (OE) is also provided; when
the chip is disabled its output is high impedance. Finally, an
open collector output flag (TOL) is provided to indicate the
status of the chip. The status flag goes low to indicate when
the chip is disabled due to either the internal Thermal
Overload shutdown or the external disable.
In order to maximize bandwidth and output drive capacity,
internal current limiting is not provided. However, current
limiting may be applied via the VC+ and VC- pins which
provide power separately to the output stage.
For Military grade product refer to the HA-5004/883 data
