HFA1109
450MHz, Low Power, Current Feedback Video Operational Amplifier
Description
The HFA1109 is a high speed, low power, current feedback amplifier built with Intersil's proprietary complementary bipolar UHF-1 process. This amplifier features a unique combination of power and performance specifically tailored for video applications. The HFA1109 is a standard pinout op amp. It is a higher performance, drop-in replacement (no feedback resistor change required) for the CLC409. If a comparably performing op amp with an output disable function (useful for video multiplexing) is required, please refer to the HFA1149 data sheet.

HFA1109 Application Information
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 HFA1109 design is optimized for a 250 RF at a gain of +2. Decreasing RF decreases stability, resulting in excessive peaking and overshoot (Note: Capacitive feedback will cause the same problems due to the feedback impedance decrease at higher frequencies). At higher gains the amplifier is more stable, so RF can be decreased in a trade-off of stability for bandwidth.

ble oscillations. In most cases, the oscillation can be avoided by placing a resistor (RS) in series with the output prior to the capacitance. RS and CL form a low pass network at the output, thus limiting system bandwidth well below the amplifier bandwidth. By decreasing RS as CL increases, the maximum bandwidth is obtained without sacrificing stability. In spite of this, bandwidth still decreases as the load capacitance increases.
Evaluation Board
The performance of the HFA1105 may be evaluated using the HFA11XX Evaluation Board and a SOIC to DIP adaptor like the Aries Electronics Part Number 14-350000-10. The layout and schematic of the board are shown in Figure 1. Please contact your local sales office for information. When evaluating this amplifier, the two 510 gain setting resistors on the evaluation board should be changed to 250.

Table 1 lists recommended RF values, and the expected bandwidth, for various closed loop gains. For a gain of +1, a resistor (+RS) in series with +IN is required to reduce gain peaking and increase stability
TOP LAYOUT
PC Board Layout
The frequency response of this amplifier depends greatly on the 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 (10F) tantalum in parallel with a small value (0.1F) chip capacitor works well in most cases. Terminated microstrip signal lines are recommended at the input and output of the device. Capacitance directly on 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 possible instability. Thus it is recommended that the ground plane be removed under traces connected to -IN, and connections to -IN should be kept as short as possible.
