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 V

provide power separately to the output stage.
