380MHz, SOT-23, Low Power Current Feedback Operational Amplifier
The HFA1155 is a low power, high-speed op amp and is the most recent addition to Intersil's HFA1XX5 series of low power op amps and buffers. Intersil's proprietary complementary bipolar UHF-1 process, coupled with the current feedback architecture deliver superb bandwidth even at very high gains (>250MHz at AV = 10). The excellent video parameters make this amplifier ideal for professional video applications. Though specified for 5V operation, the HFA1155 operates with single supply voltages as low as 4.5V, and requires only 1.4mA of ICC in 5V applications (see Application Information section, and Application Note AN9897). For a lower distortion, higher bandwidth amplifier in a SOT23 package, please refer to the HFA1150 data sheet.

5V Single Supply Operation
This amplifier operates at single supply voltages down to 4.5V. The dramatic supply current reduction at this operating condition (refer also to Figure 25) makes this op amp an even better choice for low power 5V systems. Refer to Application Note AN9897 for further information.
Performance Differences Between Packages
The HFA1155 is a high frequency current feedback amplifier. As such, it is sensitive to parasitic capacitances which influence the amplifier's operation. The different parasitic capacitances of the SOIC and SOT-23 packages yield performance differences (notably bandwidth and bandwidth related parameters) between the two devices - 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 some "Typical Performance Curves" have separate graphs for each package type. Graphs not labeled with a specific package type are applicable to both packages.
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 380MHz/355MHz (SOIC/SOT-23, AV = +2). By decreasing RS as CLincreases (as illustrated by the curves), the maximum bandwidth is obtained without sacrificing stability. In spite of this, bandwidth still decreases as the load capacitance increases. For example, at AV = +2, RS = 30, CL = 22pF, the SOIC bandwidth is 290MHz, but the bandwidth drops to 90MHz at AV = +2, RS = 6, CL = 390pF.
Optimum Feedback Resistor
The enclosed frequency response graphs detail the performance of the HFA1155 in various gains. Although the bandwidth dependency on ACL isn't as severe as that of a voltage feedback amplifier, there is an appreciable decrease in bandwidth at higher gains. This decrease can 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 the 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 HFA1155 is optimized for RF = 715/604 (SOIC/SOT-23), 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). 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.

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 (10F) tantalum in parallel with a small value chip (0.1F) capacitor works well in most cases. Terminated microstrip signal lines are recommended at the input and output of the device. Output capacitance, such as that resulting from an improperly terminated transmission line, will degrade the frequency response of the amplifier and may cause oscillations. In most cases, the oscillation can be avoided by placing a resistor in series with the output. Care must also be taken to minimize the capacitance to ground seen by the amplifier's inverting input. The larger this capacitance, the worse the gain peaking, resulting in pulse overshoot and eventual instability. To reduce this capacitance, remove the ground plane under traces connected to -IN and keep these traces as short as possible. Examples of good high frequency layouts are the evaluation boards shown below.

Evaluation Boards
The performance of the HFA1155IB (SOIC) may be evaluated using the HFA11XX Evaluation Board and a SOIC to DIP adaptor like the Aries Electronics Part Number 08-350000-10. The SOT-23 version can be evaluated using the OPAMPSOT23EVAL board. Note that the feedback and gain setting resistors on both boards must be changed to the appropriate values listed in the "Optimum Feedback Resistor" table.
