September 1998 File Number 3591.4
Quad, 125MHz Video Current Feedback Amplifier
The HA5025 is a wide bandwidth high slew rate quad amplifier 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. The performance of the HA5025 is very similar to the popular Intersil HA-5020.

NOTES: 1. Maximum power dissipation, including output load, must be designed to maintain junction temperature below 175oC for die, and below 150oC for plastic packages. See Application Information section for safe operating area information. 2. JA is measured with the component mounted on an evaluation PC board in free air. 3. The non-inverting input of unused amplifiers must be connected to GND. 4. Output is protected for short circuits to ground. Brief short circuits to ground will not degrade reliability, however, continuous (100% duty cycle) output current should not exceed 15mA for maximum reliability.

HA5025 Application Information
Optimum Feedback Resistor
The plots of inverting and non-inverting frequency response, see Figure 8 and Figure 9 in the typical performance section, illustrate the performance of the HA5025 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 HA5025 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 following table lists recommended RF values for various gains, and the expected bandwidth.

-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 6.

FIGURE 6. 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 quad amplifiers, care must be taken to insure that the maximum junction temperature (TJ , see Absolute Maximum Ratings) is not exceeded. Figure 7 shows the maximum ambient temperature versus supply voltage for the available package styles (PDIP, SOIC). At VS = 5V quiescent operation both package styles may be operated over the full industrial range of -40oC to 85oC. 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 recommended that the ground plane be removed under traces connected to
