HFA1405
March 1, 2005 FN3604.9
Quad, 560MHz, Low Power, Video Operational Amplifier
The HFA1405 is a quad, high speed, low power current feedback amplifier built with Intersil’s proprietary complementary bipolar UHF-1 process. These amplifiers deliver up to 560MHz bandwidth and 2500V/µs slew rate, on only 58mW of quiescent power. They are specifically designed to meet the performance, power, and cost requirements of high volume video applications. The excellent gain flatness and differential gain/phase performance make these amplifiers well suited for component or composite video applications. Video performance is maintained even when driving a back terminated cable (RL = 150Ω), and degrades only slightly when driving two back terminated cables (RL = 75Ω). RGB applications will benefit from the high slew rates, and high full power bandwidth. The HFA1405 is a pin compatible, low power, high performance upgrade for the popular Intersil HA5025, and for the CLC414 and CLC415.

Application Information
Performance Differences Between Packages
The amplifiers comprising the HFA1405 are high frequency current feedback amplifiers. As such, they are sensitive to feedback capacitance which destabilizes the op amp and causes overshoot and peaking. Unfortunately, the standard quad op amp pinout places the amplifier’s output next to its inverting input, thus making the package capacitance an unavoidable parasitic feedback capacitor. The larger
parasitic capacitance of the PDIP requires an inherently more stable amplifier, which yields a PDIP device with lower performance than the SOIC device - see Electrical Specification tables for details. Because of these performance differences, designers should evaluate and breadboard with the same package style to be used in production. Note that the “Typical Performance Curves” section has separate pulse and frequency response graphs for each

package type. Graphs not labeled with a specific package type are applicable to all packages. resulting in added distortion for signals swinging below ground, and an increased undershoot on the negative portion of the output waveform (see Figure 6 and Figure 9). This undershoot isn’t present for small bipolar signals, or large positive signals (see Figure 4 and Figure 5).
Optimum Feedback Resistor
Although a current feedback amplifier’s 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 HFA1405 design is optimized for RF = 402Ω/510Ω (PDIP/SOIC) at a gain of +2. Decreasing RF decreases stability, resulting in excessive peaking and overshoot (Note: Capacitive feedback causes the same problems due to the feedback impedance decrease at higher frequencies). However, 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. For good channel-tochannel gain matching, it is recommended that all resistors (termination as well as gain setting) be ±1% tolerance or better.

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, while a solid ground plane is a must! Attention should be given to decoupling the power supplies. A large value (10µF) tantalum in parallel with a small value (0.1µF) chip capacitor works well in most cases. Terminated microstrip signal lines are recommended at the input and output of the device. Capacitance, parasitic or planned, connected to the output must be minimized, or isolated as discussed in the next section. Care must also be taken to minimize the capacitance to ground at the amplifier’s inverting input (-IN). The larger this capacitance, the worse the gain peaking, resulting in pulse overshoot and eventual instability. To reduce this capacitance the designer should remove the ground plane under traces connected to -IN, and keep connections to -IN as short as possible. An example of a good high frequency layout is the Evaluation Board shown in Figure 3.
Driving Capacitive Loads
Capacitive loads, such as an A/D input, or an improperly terminated transmission line 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 a resistor (RS) in series with the output prior to the capacitance. Figure 1 details starting points for the selection of this resistor. The points on the curve indicate the RS and CL combinations for the optimum bandwidth, stability, and settling time, but experimental fine tuning is recommended. Picking a point above or to the right of the curve yields an overdamped response, while points below or left of the curve indicate areas of underdamped performance. RS and CL form a low pass network at the output, thus limiting system bandwidth well below the amplifier bandwidth of 560MHz. By decreasing RS as CL increases (as illustrated in the curve), the maximum bandwidth is obtained without sacrificing stability. In spite of this, bandwidth still decreases as the load capacitance increases.
NOTE: RF = 500Ω is not the optimum value. It was chosen to match the RF of the CLC414 and CLC415, for performance comparison purposes. Performance at AV = +6 may be increased by reducing RF below 500Ω.
Non-inverting Input Source Impedance
For best operation, the DC source impedance seen by the non-inverting input should be ≥ 50Ω. This is especially important in inverting gain configurations where the noninverting input would normally be connected directly to GND.
Pulse Undershoot
The HFA1405 utilizes a quasi-complementary output stage to achieve high output current while minimizing quiescent supply current. In this approach, a composite device replaces the traditional PNP pulldown transistor. The composite device switches modes after crossing 0V,

Evaluation Board
The performance of the HFA1405 PDIP or SOIC can be evaluated using the HA5025 Evaluation Board. The HFA1405IB (SOIC) requires a SOIC to DIP adaptor like the Aries Electronics Part Number 14-350000-10. The schematic for the PDIP/SOIC amplifier 1 and the HA5025EVAL board layout are shown in Figure 2 and Figure 3. Resistors RF, RG , and +RS may require a change to values applicable to the HFA1405.

NOTES: 1. Symbols are defined in the “MO Series Symbol List” in Section 2.2 of Publication Number 95. 2. Dimensioning and tolerancing per ANSI Y14.5M-1982. 3. Dimension “D” does not include mold flash, protrusions or gate burrs. Mold flash, protrusion and gate burrs shall not exceed 0.15mm (0.006 inch) per side. 4. Dimension “E” does not include interlead flash or protrusions. Interlead flash and protrusions shall not exceed 0.25mm (0.010 inch) per side. 5. The chamfer on the body is optional. If it is not present, a visual index feature must be located within the crosshatched area. 6. “L” is the length of terminal for soldering to a substrate. 7. “N” is the number of terminal positions. 8. Terminal numbers are shown for reference only. 9. The lead width “B”, as measured 0.36mm (0.014 inch) or greater above the seating plane, shall not exceed a maximum value of 0.61mm (0.024 inch). 10. Controlling dimension: MILLIMETER. Converted inch dimensions are not necessarily exact.

NOTES: 1. Controlling Dimensions: INCH. In case of conflict between English and Metric dimensions, the inch dimensions control. 2. Dimensioning and tolerancing per ANSI Y14.5M-1982. 3. Symbols are defined in the “MO Series Symbol List” in Section 2.2 of Publication No. 95. 4. Dimensions A, A1 and L are measured with the package seated in JEDEC seating plane gauge GS-3. 5. D, D1, and E1 dimensions do not include mold flash or protrusions. Mold flash or protrusions shall not exceed 0.010 inch (0.25mm). 6. E and eA are measured with the leads constrained to be perpendicular to datum -C- . 7. eB and eC are measured at the lead tips with the leads unconstrained. eC must be zero or greater. 8. B1 maximum dimensions do not include dambar protrusions. Dambar protrusions shall not exceed 0.010 inch (0.25mm). 9. N is the maximum number of terminal positions. 10. Corner leads (1, N, N/2 and N/2 + 1) for E8.3, E16.3, E18.3, E28.3, E42.6 will have a B1 dimension of 0.030 - 0.045 inch (0.76 1.14mm).
