HFA1405 September 1998 File Number 3604.5 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 1700V/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.

The optimum feedback resistor depends on closed loop gain and package type. The following resistors were used for the PDIP/SOIC characterization: AV = -1, RF = 310Ω/360Ω; AV = +2, RF = 402Ω/510Ω; AV = +6, RF = 500Ω/500Ω. See the Application Information section for more information. 4. Test Level: A. Production Tested; B. Typical or Guaranteed Limit Based on Characterization; C. Design Typical for Information Only. 5. See Typical Performance Curves for more information. 6. Undershoot dominates for output signal swings below GND (e.g., 2VP-P), yielding a higher overshoot limit compared to the VOUT = 0V to 2V condition. See the “Application Information” section for details. 25 25 Full ±4.5 5.8 5.9 ±5.5 6.1 6.3 ±4.5 5.8 5.9 ±5.5 6.1 6.3 V mA/Op Amp mA/Op Amp 4 HFA1405 Application Information Performance Differences Between PDIP and SOIC 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 both packages. 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, 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 5 and Figure 8). 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. OPTIMUM FEEDBACK RESISTOR GAIN (ACL) -1 +2 +6 RF (Ω) PDIP/SOIC 310/360 402/510 500/500 (Note) BANDWIDTH (MHz) PDIP/SOIC 360/420 400/560 100/140 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 seen by 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. 5 HFA1405 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. 50 SERIES OUTPUT RESISTANCE (Ω) RS 50Ω OUT RG IN 50Ω RF 1 2 3 4 5 +5V 10µF 0.1µF 6 7 9 8 GND GND + 14 13 12 11 10 0.1µF 10µF -5V FIGURE 2.
