HA5022 T UCT R OD RODU C P E P T E E OL UT O B S U B S TI T 5 S 4 2 E FA 1 IBL DataHSheet O SS (R) P Dual, 125MHz, Video Current Feedback Amplifier with Disable The HA5022 is a dual version of the popular Intersil HA5020. 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 HA5022 also features a disable function that significantly reduces supply current while forcing the output to a true high impedance state. This functionality allows 2:1 video multiplexers to be implemented with a single IC. 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.

Optimum Feedback Resistor The plots of inverting and non-inverting frequency response, see Figure 11 and Figure 12 in the Typical Performance Curves section, illustrate the performance of the HA5022 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 HA5022 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.

In most cases the oscillation can be avoided by placing an isolation resistor (R) in series with the output as shown in Figure 6. 100 VIN R + VOUT - RT CL RF RI 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 dual 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 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 -IN, and that connections to -IN be kept 7 140 MAX. AMBIENT TEMPERATURE 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. 130 PDIP 120 110 100 90 SOIC 80 5 7 9 11 13 15 SUPPLY VOLTAGE (V) FIGURE 7. MAXIMUM OPERATING AMBIENT TEMPERATURE vs SUPPLY VOLTAGE Enable/Disable Function When enabled the amplifier functions as a normal current feedback amplifier with all of the data in the electrical specifications table being valid and applicable. When HA5022 disabled the amplifier output assumes a true high impedance state and the supply current is reduced significantly. The circuit shown in Figure 8 is a simplified schematic of the enable/disable function. The large value resistors in series with the DISABLE pin makes it appear as a current source to the driver. When the driver pulls this pin low current flows out of the pin and into the driver. This current, which may be as large as 350A when external circuit and process variables are at their extremes, is required to insure that point "A" achieves the proper potential to disable the output. The driver must have the compliance and capability of sinking all of this current. V+ R6 15K R10 R33 QP18 D1 R8 R7 15K A QP3 ENABLE/DISABLE INPUT FIGURE 8. SIMPLIFIED SCHEMATIC OF ENABLE/DISABLE FUNCTION When VCC is +5V the DISABLE pin may be driven with a dedicated TTL gate. The maximum low level output voltage of the TTL gate, 0.4V, has enough compliance to insure that the amplifier will always be disabled even though D1 will not turn on, and the TTL gate will sink enough current to keep point "A" at its proper voltage. When VCC is greater than +5V the DISABLE pin should be driven with an open collector device that has a breakdown rating greater than VCC . Referring to Figure 8, it can be seen that R6 will act as a pullup resistor to +VCC if the DISABLE pin is left open. In those cases where the enable/disable function is not required on all circuits some circuits can be permanently enabled by letting the DISABLE pin float. If a driver is used to set the enable/disable level, be sure that the driver does not sink more than 20A when the DISABLE pin is at a high level. TTL gates, especially CMOS versions, do not violate this criteria so it is permissible to control the enable/disable function with TTL. Typical Applications Two Channel Video Multiplexer Referring to the amplifier U1A in Figure 9, R1 terminates the cable in its characteristic impedance of 75, and R4 back terminates the cable in its characteristic impedance. The amplifier is set up in a gain configuration of +2 to yield an overall network gain of +1 when driving a double terminated cable. The value of R3 can be changed if a different network gain is desired. R5 holds the disable pin at ground thus inhibiting the amplifier until the switch, S1, is thrown to 8 position 1. At position 1 the switch pulls the disable pin up to the plus supply rail thereby enabling the amplifier. Since all of the actual signal switching takes place within the amplifier, it's differential gain and phase parameters, which are 0.03% and 0.03 degrees respectively, determine the circuit's performance. The other circuit, U1B, operates in a similar manner. When the plus supply rail is 5V the disable pin can be driven by a dedicated TTL gate as discussed earlier. If a multiplexer IC or its equivalent is used to select channels its logic must be break before make. When these conditions are satisfied the HA5022 is often used as a remote video multiplexer, and the multiplexer may be extended by adding more amplifier ICs. Low Impedance Multiplexer Two common problems surface when you try to multiplex multiple high speed signals into a low impedance source such as an A/D converter. The first problem is the low source impedance which tends to make amplifiers oscillate and causes gain errors. The second problem is the multiplexer which supplies no gain, introduces all kinds of distortion and limits the frequency response. Using op amps which have an enable/disable function, such as the HA5022, eliminates the multiplexer problems because the external mux chip is not needed, and the HA5022 can drive low impedance (large capacitance) loads if a series isolation resistor is used. Referring to Figure 10, both inputs are terminated in their characteristic impedance; 75 is typical for video applications. Since the drivers usually are terminated in their characteristic impedance the input gain is 0.5, thus the amplifiers, U2, are configured in a gain of +2 to set the circuit gain equal to one. Resistors R2 and R3 determine the amplifier gain, and if a different gain is desired R2 should be changed according to the equation G = (1 + R3/R2). R3 sets the frequency response of the amplifier so you should refer to the manufacturers data sheet before changing its value. R5, C1 and D1 are an asymmetrical charge/discharge time circuit which configures U1 as a break before make switch to prevent both amplifiers from being active simultaneously. If this design is extended to more channels the drive logic must be designed to be break before make. R4 is enclosed in the feedback loop of the amplifier so that the large open loop amplifier gain of U2 will present the load with a small closed loop output impedance while keeping the amplifier stable for all values of load capacitance. The circuit shown in Figure 10 was tested for the full range of capacitor values with no oscillations being observed; thus, problem one has been solved.The frequency and gain characteristics of the circuit are now those of the amplifier independent of any multiplexing action; thus, problem two has been solved. The multiplexer transition time is approximately 15s with the component values shown.
