EL5166, EL5167 ® Data Sheet May 15, 2007 1.4GHz Current Feedback Amplifiers with Enable The EL5166 and EL5167 amplifiers are of the current feedback variety and exhibit a very high bandwidth of 1.4GHz at AV = +1 and 800MHz at AV = +2. This makes these amplifiers ideal for today's high speed video and monitor applications, as well as a number of RF and IF frequency designs. With a supply current of just 8.5mA and the ability to run from a single supply voltage from 5V to 12V, these amplifiers offer very high performance for little power consumption. FN7365.5 Features • Gain-of-1 bandwidth = 1.4GHz/gain-of-2 bandwidth = 800MHz • 6000V/µs slew rate • Single and dual supply operation from 5V to 12V • Low noise = 1.5nV/√Hz • 8.5mA supply current • Fast enable/disable (EL5166 only) • 600MHz family - (EL5164 and EL5165) The EL5166 also incorporates an enable and disable function to reduce the supply current to 13µA typical per amplifier.

The EL5166 and EL5167 work with supply voltages ranging from a single 5V to 10V and they are also capable of swinging to within 1V of either supply on the output. Because of their currentfeedback topology, the EL5166 and EL5167 do not have the normal gain-bandwidth product associated with voltagefeedback operational amplifiers. Instead, their -3dB bandwidth remains relatively constant as closed-loop gain is increased. This combination of high bandwidth and low power, together with aggressive pricing make the EL5166 and EL5167 ideal choices for many low-power/highbandwidth applications such as portable, handheld, or battery-powered equipment. Power Supply Bypassing and Printed Circuit Board Layout As with any high frequency device, good printed circuit board layout is necessary for optimum performance. Low impedance ground plane construction is essential. Surface mount components are recommended, but if leaded components are used, lead lengths should be as short as possible. The power supply pins must be well bypassed to reduce the risk of oscillation. The combination of a 4.7µF tantalum capacitor in parallel with a 0.01µF capacitor has been shown to work well when placed at each supply pin. For good AC performance, parasitic capacitance should be kept to a minimum, especially at the inverting input. (See the Capacitance at the Inverting Input section) Even when ground plane construction is used, it should be removed from the area near the inverting input to minimize any stray capacitance at that node. Carbon or Metal-Film resistors are acceptable with the Metal-Film resistors giving slightly less peaking and bandwidth because of additional series inductance. Use of sockets, particularly for the SO package, should be avoided if possible. Sockets add parasitic inductance and capacitance which will result in additional peaking and overshoot. Disable/Power-Down The EL5166 amplifier can be disabled placing its output in a high impedance state. When disabled, the amplifier supply current is reduced to 13µA. The EL5166 is disabled when its CE pin is pulled up to within 1V of the positive supply. Similarly, the amplifier is enabled by floating or pulling its CE pin to at least 3V below the positive supply. For ±5V supply, this means that an EL5166 amplifier will be enabled when CE is 2V or less, and disabled when CE is above 4V. Although the logic levels are not standard TTL, this choice of logic voltages allows the EL5166 to be enabled by tying CE to ground, even in 5V single supply applications. The CE pin can be driven from CMOS outputs. 10 Capacitance at the Inverting Input Any manufacturer’s high-speed voltage- or current-feedback amplifier can be affected by stray capacitance at the inverting input. For inverting gains, this parasitic capacitance has little effect because the inverting input is a virtual ground. But for non-inverting gains, this capacitance (in conjunction with the feedback and gain resistors) creates a pole in the feedback path of the amplifier. This pole, if low enough in frequency, has the same destabilizing effect as a zero in the forward open-loop response. The use of large value feedback and gain resistors exacerbates the problem by further lowering the pole frequency (increasing the possibility of oscillation). The EL5166 and EL5167 frequency responses are optimized with the resistor values in Figure 3. With the high bandwidth of these amplifiers, these resistor values might cause stability problems when combined with parasitic capacitance, thus ground plane is not recommended around the inverting input pin of the amplifier. Feedback Resistor Values The EL5166 and EL5167 have been designed and specified at a gain of +2 with RF approximately 392Ω. This value of feedback resistor gives 800MHz of -3dB bandwidth at AV = 2 with about 0.5dB of peaking. Since the EL5166 and EL5167 are current-feedback amplifiers, it is also possible to change the value of RF to get more bandwidth. As seen in the curve of Frequency Response for Various RF and RG, bandwidth and peaking can be easily modified by varying the value of the feedback resistor. Because the EL5166 and EL5167 are current-feedback amplifiers, their gain-bandwidth product is not a constant for different closed-loop gains. This feature actually allows the EL5166 and EL5167 to maintain reasonable constant -3dB bandwidth for different gains. As gain is increased, bandwidth decreases slightly while stability increases. Since the loop stability is improving with higher closed-loop gains, it becomes possible to reduce the value of RF below the specified 250Ω and still retain stability, resulting in only a slight loss of bandwidth with increased closed-loop gain. Supply Voltage Range and Single-Supply Operation The EL5166 and EL5167 have been designed to operate with supply voltages having a span of greater than 5V and less than 10V. In practical terms, this means that the EL5166 and EL5167 will operate on dual supplies ranging from ±2.5V to ±5V. With single-supply, they will operate from 5V to 10V. As supply voltages continue to decrease, it becomes necessary to provide input and output voltage ranges that can get as close as possible to the supply voltages. The EL5166 and EL5167 have an input range which extends to within 1.8V of either supply. So, for example, on ±5V supplies, the EL5166 and EL5167 have an input range FN7365.5 May 15, 2007 EL5166, EL5167 which spans ±3.2V. The output range of the EL5166 and EL5167 is also quite large, extending to within 1V of the supply rail. On a ±5V supply, the output is therefore capable of swinging from -4V to +4V. Video Performance For good video performance, an amplifier is required to maintain the same output impedance and the same frequency response as DC levels are changed at the output. This is especially difficult when driving a standard video load of 150Ω, because of the change in output current with DC level. Previously, good differential gain could only be achieved by running high idle currents through the output transistors (to reduce variations in output impedance.) These currents were typically comparable to the entire 8.5mA supply current of each EL5166 and EL5167 amplifier. Special circuitry has been incorporated in the EL5166 and EL5167 to reduce the variation of output impedance with current output. This results in dG and dP specifications of 0.01% and 0.03°, while driving 150Ω at a gain of 2. Output Drive Capability about 25Ω, it is important to calculate the maximum junction temperature (TJMAX) for the application to determine if power supply voltages, load conditions, or package type need to be modified for the EL5166 and EL5167 to remain in the safe operating area. These parameters are calculated as follows: T JMAX = T MAX + ( θ JA × n × PD MAX ) where: TMAX = Maximum ambient temperature θJA = Thermal resistance of the package n = Number of amplifiers in the package PDMAX = Maximum power dissipation of each amplifier in the package PDMAX for each amplifier can be calculated as follows: V OUTMAX PD MAX = ( 2 × V S × I SMAX ) + ( V S – V OUTMAX ) × ---------------------------R L where: In spite of their low 8.5mA of supply current, the EL5166 and EL5167 are capable of providing a minimum of ±110mA of output current. With so much output drive, the EL5166 and EL5167 are capable of driving 50Ω loads to both rails, making them an excellent choice for driving isolation transformers in telecommunications applications. VS = Supply voltage ISMAX = Maximum supply current of 1A VOUTMAX = Maximum output voltage (required) RL = Load resistance Driving Cables and Capacitive Loads When used as a cable driver, double termination is always recommended for reflection-free performance. For those applications, the back-termination series resistor will decouple the EL5166 and EL5167 from the cable and allow extensive capacitive drive. However, other applications may have high capacitive loads without a back-termination resistor. In these applications, a small series resistor (usually between 5Ω and 50Ω) can be placed in series with the output to eliminate most peaking. The gain resistor (RG) can then be chosen to make up for any gain loss which may be created by this additional resistor at the output. In many cases it is also possible to simply increase the value of the feedback resistor (RF) to reduce the peaking. Current Limiting The EL5166 and EL5167 have no internal current-limiting circuitry. If the output is shorted, it is possible to exceed the Absolute Maximum Rating for output current or power dissipation, potentially resulting in the destruction of the device. Power Dissipation With the high output drive capability of the EL5166 and EL5167, it is possible to exceed the 125°C Absolute Maximum junction temperature under certain very high load current conditions.
