Description
The HA-5004/883 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 oper-
ational amplifiers. Since feedback is employed, the HA-5004/883
can offer better gain accuracy and lower distortion than open
loop buffers. Unlike conventional op amps, the bandwidth and
rise time of the HA-5004/883 are nearly independent of closed
loop gain. The 100MHz bandwidth at unity gain reduces to only
65MHz at a gain of 10. The HA-5004/883 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 ther-
mal 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) input is also provided; when the chip is dis-
abled its output is high impedance. Finally, an open collector out-
put 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, inter-
nal current limiting is not provided. However, current limiting may
be applied via the V
rately to the output stage.
