This buffer is the ideal choice for high frequency applications requiring output limiting, especially those needing ultra fast overload recovery times. The output limiting function allows the designer to set the maximum positive and negative output levels, thereby protecting later stages from damage or input saturation. The sub-nanosecond overdrive recovery time quickly returns the amplifier to linear operation following an overdrive condition. A unique feature of the pinout allows the user to select a voltage gain of +1, -1, or +2, without the use of any external components, as described in the “Application Information” section. Compatibility with existing op amp pinouts provides flexibility to upgrade low gain amplifiers, while decreasing component count. Unlike most buffers, the standard pinout provides an upgrade path should a higher closed loop gain be needed at a future date.

Application Information Closed Loop Gain Selection The HFA1113 features a novel design which allows the user to select from three closed loop gains, without any external components. The result is a more flexible product, fewer part types in inventory, and more efficient use of board space. This “buffer” operates in closed loop gains of -1, +1, or +2, and gain selection is accomplished via connections to the Inputs. Applying the input signal to +IN and floating -IN selects a gain of +1, while grounding -IN selects a gain of +2. A gain of -1 is obtained by applying the input signal to -IN with +IN grounded. The table below summarizes these connections: CONNECTIONS 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 850MHz. By decreasing RS as CLincreases (as illustrated in the curves), the maximum bandwidth is obtained without sacrificing stability. Even so, bandwidth does decrease as you move to the right along the curve. For example, at AV = +1, RS = 50, CL = 30pF, the overall bandwidth is limited to 300MHz, and bandwidth drops to 100MHz at AV = +1, RS = 5, CL = 340pF. GAIN (ACL) +INPUT (PIN 3) -INPUT (PIN 2) -1 GND Input +1 Input NC (Floating) 50 +2 Input GND 45 AV = +1 40 35 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! 30 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. Capacitance directly on the output must be minimized, or isolated as discussed in the next section. For unity gain applications, care must also be taken to minimize the capacitance to ground seen by the amplifier’s inverting input. At higher frequencies this capacitance will tend to short the -INPUT to GND, resulting in a closed loop gain which increases with frequency. This will cause excessive high frequency peaking and potentially other problems as well. 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 5 RS () PC Board Layout 25 20 15 10 5 AV = +2 0 0 40 80 120 160 200 240 280 320 360 400 LOAD CAPACITANCE (pF) FIGURE 1. RECOMMENDED SERIES RESISTOR vs LOAD CAPACITANCE Evaluation Board The performance of the HFA1113 may be evaluated using the HFA11XX Evaluation Board, slightly modified as follows: 1. Remove the 500 feedback resistor (R2), and leave the connection open. 2. a. For AV = +1 evaluation, remove the 500 gain setting resistor (R1), and leave pin 2 floating. b. For AV = +2, replace the 500 gain setting resistor with a 0 resistor to GND. The modified schematic and layout of the board are shown in Figures 2 and 3. To order evaluation boards (part number HFA11XXEVAL), please contact your local sales office.

MODIFIED EVALUATION BOARD SCHEMATIC TOP LAYOUT This current is mirrored onto the high impedance node (Z) by QX3-QX4, where it is converted to a voltage and fed to the output via another unity gain buffer. If no clamping is utilized, the high impedance node may swing within the limits defined by QP4 and QN4. Note that when the output reaches its quiescent value, the current flowing through -IN is reduced to only that small current (-IBIAS) required to keep the output at the final voltage. Tracing the path from VH to Z illustrates the effect of the clamp voltage on the high impedance node. VH decreases by 2VBE (QN6 and QP6) to set up the base voltage on QP5.

HFA1113 SIMPLIFIED VH CLAMP CIRCUITRY FIGURE 3. EVALUATION BOARD LAYOUT Limiting Operation General The HFA1113 features user programmable output clamps to limit output voltage excursions. Clamping action is obtained by applying voltages to the VH and VL terminals (pins 8 and 5) of the amplifier. VH sets the upper output limit, while VL sets the lower clamp level. If the amplifier tries to drive the output above VH, or below VL, the clamp circuitry limits the output voltage at VH or VL ( the clamp accuracy), respectively. The low input bias currents of the clamp pins allow them to be driven by simple resistive divider circuits, or active elements such as amplifiers or DACs. Clamp Circuitry Figure 4 shows a simplified schematic of the HFA1113 input stage, and the high clamp (VH) circuitry. As with all current feedback amplifiers, there is a unity gain buffer (QX1 - QX2) 6 QP5 begins to conduct whenever the high impedance node reaches a voltage equal to QP5’s base voltage + 2VBE (QP5 and QN5). Thus, QP5 clamps node Z whenever Z reaches VH. R1 provides a pull-up network to ensure functionality with the clamp inputs floating. A similar description applies to the symmetrical low clamp circuitry controlled by VL. When the output is clamped, the negative input continues to source a slewing current (ICLAMP) in an attempt to force the output to the quiescent voltage defined by the input. QP5 must sink this current while clamping, because the -IN current is always mirrored onto the high impedance node. The clamping current is calculated as: ICLAMP = (V-IN - VOUT CLAMPED)/300 + V-IN/RG. As an example, a unity gain circuit with VIN = 2V, and VH = 1V, would have ICLAMP = (2V - 1V)/300 + 2V/ = 3.33mA (RG = because -IN is floated for unity gain applications). Note that ICC will increase by ICLAMP when the output is clamp limited. FN1342.6 July 11, 2005 HFA1113 Clamp Accuracy The clamped output voltage will not be exactly equal to the voltage applied to VH or VL. Offset errors, mostly due to VBE mismatches, necessitate a clamp accuracy parameter which is found in the device specifications. Clamp accuracy is a function of the clamping conditions. Referring again to Figure 4, it can be seen that one component of clamp accuracy is the VBE mismatch between the QX6 transistors, and the QX5 transistors. If the transistors always ran at the same current level there would be no VBE mismatch, and no contribution to the inaccuracy. The QX6 transistors are biased at a constant current, but as described earlier, the current through QX5 is equivalent to ICLAMP. VBE increases as ICLAMP increases, causing the clamped output voltage to increase as well. ICLAMP is a function of the overdrive level (AVCL x VIN - VOUT CLAMPED), so clamp accuracy degrades as the overdrive increases. As an example, the specified accuracy of 100mV (AV = -1, VH = 1V) for a 1.6X overdrive degrades to 240mV for a 3X (200%) overdrive, as shown in Figure 43. Consideration must also be given to the fact that the clamp voltages have an affect on amplifier linearity. The “Nonlinearity Near Clamp Voltage” curve, Figure 48, illustrates the impact of several clamp levels on linearity. Clamp Range Unlike some competitor devices, both VH and VL have usable ranges that cross 0V. While VH must be more positive than VL , both may be positive or negative, within the Typical Performance Curves range restrictions indicated in the specifications. For example, the HFA1113 could be limited to ECL output levels by setting VH = -0.8V and VL = -1.8V. VH and VL may be connected to the same voltage (GND for instance) but the result won’t be in a DC output voltage from an AC input signal. A 150mV - 200mV AC signal will still be present at the output. Recovery from Overdrive The output voltage remains at the clamp level as long as the overdrive condition remains. When the input voltage drops below the overdrive level (VCLAMP/AVCL) the amplifier will return to linear operation. A time delay, known as the Overdrive Recovery Time, is required for this resumption of linear operation. The plots of “Unclamped Performance” and “Clamped Performance” (Figures 41 and 42) highlight the HFA1113’s subnanosecond recovery time. The difference between the unclamped and clamped propagation delays is the overdrive recovery time. The appropriate propagation delays are 8.0ns for the unclamped pulse, and 8.8ns for the clamped (2X overdrive) pulse yielding an overdrive recovery time of 800ps. The measurement uses the 90% point of the output transition to ensure that linear operation has resumed. Note: The propagation delay illustrated is dominated by the fixturing. The delta shown is accurate, but the true HFA1113 propagation delay is 500ps. Overdrive recovery time is also a function of the overdrive level. Figure 47 details the overdrive recovery time for various clamp and overdrive levels.
