100MHz Current Feedback Amplifier

The HA-5004 current feedbackamplifierisavideo/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).ATTLchipenable/disable(

HA-5004

Application Information

Theory Of Operation

The HA-5004 is a high performance amplifier that uses
current feedback to achieve its outstanding performance.
Although it is externally configured like an ordinary op amp
in most applications, its internal operation is significantly
different.

Inside the HA-5004, there is a unity gain buffer from the non­inverting (+) input to the inverting-input (as suggested by the
circuit symbol), and the inverting terminal is a low
impedance point. Error currents are sensed at the inverting
input and amplified; a small change in input current
produces a large change in output voltage. The ratio of
output voltage delta due to input current delta is the
transimpedance of the device.

Steady state current at the inverting input is very small
because the transimpedance is large. The voltage across
the input terminals is nearly zero due to the buffer amplifier.
These two properties are similar to standard op amps and
likewise simplify circuit analysis.

Resistor Selection

The HA-5004 is optimized for a feedback resistor of 250Ω,
regardless of gain configuration. It is important to note that
this resistor is required even for unity gain applications;
higher gain settings use a second resistor like regular op
amp circuits as shown in Figure 2 below.

Current Limit

No internal current limiting is provided for the HA-5004 in
order to maximize bandwidth and slew rate. However, power
is supplied separately to the output stage via pins 1 (V

recommended.

Enable/Disable and Thermal
Overload Operation

The HA-5004 operates normally with a TTL low state on pin
7 (

OE) but it may be disabled manually by a TTL high state
at this input. When disabled, the output and inverting-input
go to a high impedance state and the circuit is electrically
debiased, reducing supply current by about 5mA. It is
important to keep the differential input voltage below the
absolute maximum rating of 5V when the device is disabled.

If the power dissipation becomes excessive and chip
temperatureexceeds approximately180

o

C,the HA-5004 will
automatically disable itself. The thermal overload condition
will be indicated by a low state at the

thermal shutdown can be bypassed by a TTL high state on
Thermal Overload Inhibit (TOI)pin 6. See the truth table for a
summary of operation.

Offset Adjustment

Offset voltage may be nulled with a 5kΩ potentiometer
between pins 3 and 4, center tapped to the positive supply.
Setting the slider towards pin 3 (+BAL) increases output
voltage; towards pin 4 (-BAL) decreases output voltage.
Offset can be adjusted by about
