Dual 125MHz Video Current Feedback Amplifier
Description
The HA5023/883 is a dual version of the popular Intersil HA-5020/883 except that it does not have an enable function. It features wide bandwidth and high slew rate, and is optimized for video applications and gains between 1 and 10. It is a current feedback amplifier and thus yields less bandwidth degradation at high closed loop gains than voltage feedback amplifiers. The low differential gain and phase, 0.1dB gain flatness, and ability to drive two back terminated 75 cables, make this amplifier ideal for demanding video applications. The current feedback design allows the user to take advantage of the amplifier's bandwidth dependency on the feedback resistor. By reducing RF , the bandwidth can be increased to compensate for decreases at higher closed loop gains or heavy output loads.

Application Information
Optimum Feedback Resistor The plots of inverting and non-inverting frequency response, see Figure 1 and Figure 2 in the typical performance section, illustrate the performance of the HA5023 in various closed loop gain configurations. Although the bandwidth dependency on closed loop gain isn't as severe as that of a voltage feedback amplifier, there can be an appreciable decrease in bandwidth at higher gains. This decrease may be minimized by taking advantage of the current feedback amplifier's unique relationship between bandwidth and RF . All current feedback amplifiers require a feedback resistor, even for unity gain applications, and RF , in conjunction with the internal compensation capacitor, sets the dominant pole of the frequency response. Thus, the amplifier's bandwidth is inversely proportional to RF . The HA5023 design is optimized for a 1000 RF at a gain of +1. Decreasing RF in a unity gain application decreases stability, resulting in excessive peaking and overshoot. At higher gains the amplifier is more stable, so RF can be decreased in a trade-off of stability for bandwidth. The table below lists recommended RF values for various gains, and the expected bandwidth.
GAIN (ACL) -1 +1 +2 +5 +10 -10 RF () 750 1000 681 1000 383 750 BANDWIDTH (MHz) 100 125 95 52 65 22
mended that the ground plane be removed under traces connected to -IN, and that connections to -IN be kept as short as possible to minimize the capacitance from this node to ground.
Driving Capacitive Loads
Capacitive loads will degrade the amplifier's phase margin resulting in frequency response peaking and possible oscillations. In most cases the oscillation can be avoided by placing an isolation resistor (R) in series with the output as shown in Figure 34.

FIGURE 34. PLACEMENT OF THE OUTPUT ISOLATION RESISTOR, R
The selection criteria for the isolation resistor is highly dependent on the load, but 27 has been determined to be a good starting value.
Power Dissipation Considerations
Due to the high supply current inherent in dual amplifiers, care must be taken to insure that the maximum junction temperature (TJ , see Absolute Maximum Ratings) is not exceeded. Figure 35 shows the maximum ambient temperature versus supply voltage for the available package styles. It is recommended that thermal calculations, which take into account output power, be performed by the designer.

PC Board Layout
The frequency response of this amplifier depends greatly on the amount of care taken in designing the PC board. The use of low inductance components such as chip resistors and chip capacitors is strongly recommended. If leaded components are used the leads must be kept short especially for the power supply decoupling components and those components connected to the inverting input. Attention must be given to decoupling the power supplies. A large value (10F) tantalum or electrolytic capacitor in parallel with a small value (0.1F) chip capacitor works well in most cases. A ground plane is strongly recommended to control noise. Care must also be taken to minimize the capacitance to ground seen by the amplifier's inverting input (-IN). The larger this capacitance, the worse the gain peaking, resulting in pulse overshoot and possible instability. It is recom-
