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 sheet.
