EL5164, EL5165, EL5364 ® Data Sheet October 29, 2007 600MHz Current Feedback Amplifiers with Enable The EL5164, EL5165, and EL5364 are current feedback amplifiers with a very high bandwidth of 600MHz. This makes these amplifiers ideal for today’s high speed video and monitor applications. With a supply current of just 5mA and the ability to run from a single supply voltage from 5V to 12V, the amplifiers are also ideal for hand held, portable or battery-powered equipment. The EL5164 also incorporates an enable and disable function to reduce the supply current to 100µA typical per amplifier. Allowing the CE pin to float or applying a low logic level will enable the amplifier. The EL5165 is offered in the 5 Ld SOT-23 and 5 Ld SC-70 packages, EL5164 is available in the 6 Ld SOT-23 and the industry-standard 8 Ld SOIC packages, and the EL5364 in a 16 Ld SOIC and 16 Ld QSOP packages. All operate over the industrial temperature range of -40°C to +85°C.

VS+ CE VSCIRCUIT 3 Applications Information Product Description The EL5164, EL5165, and EL5364 are current-feedback operational amplifiers that offers a wide -3dB bandwidth of 600MHz and a low supply current of 5mA per amplifier. The EL5164, EL5165, and EL5364 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 current-feedback topology, the EL5164, EL5165, and EL5364 do not have the normal gain-bandwidth product associated with voltage-feedback operational amplifiers. Instead, its -3dB bandwidth to remain relatively constant as closed-loop gain is increased. This combination of high bandwidth and low power, together with aggressive pricing make the EL5164, EL5165, and EL5364 ideal choices for many low-power/high-bandwidth applications such as portable, handheld, or battery-powered equipment. For varying bandwidth needs, consider the EL5166 and EL5167 with 1GHz on a 8.5mA supply current or the EL5162 and EL5163 with 300MHz on a 1.5mA supply current. Versions include single, dual, and triple amp packages with 9 5 Ld SOT-23, 16 Ld QSOP, and 8 Ld SOIC or 16 Ld SOIC outlines. 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” on page 10). 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 FN7389.8 October 29, 2007 EL5164, EL5165, EL5364 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 EL5164 amplifier can be disabled placing its output in a high impedance state. When disabled, the amplifier supply current is reduced to <150µA. The EL5164 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 EL5164 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 EL5164 to be enabled by tying CE to ground, even in 5V single supply applications. The CE pin can be driven from CMOS outputs. When the amplifier is disabled, if the positive input is driven beyond ±2V with respect to the negative input, the device can become active and output the signal. An input diode clamp network D1 and D2, as shown in Figure 23, can be used to keep the device disabled while a large input signal is present. RG +5V D2 + VIN CE +5V VOUT -5V FIGURE 23. DISABLED AMPLIFIER 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 largevalue feedback and gain resistors exacerbates the problem by further lowering the pole frequency (increasing the possibility of oscillation.) The EL5164, EL5165, and EL5364 have been optimized with a 510Ω feedback resistor. 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. 10 The EL5164, EL5165, and EL5364 have been designed and specified at a gain of +2 with RF approximately 412Ω. This value of feedback resistor gives 300MHz of -3dB bandwidth at AV = 2 with 2dB of peaking. With AV = -2, an RF of 300Ω gives 275MHz of bandwidth with 1dB of peaking. Since the EL5164, EL5165, and EL5364 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 EL5164, EL5165, and EL5364 are current-feedback amplifiers, their gain-bandwidth product is not a constant for different closed-loop gains. This feature actually allows the EL5164, EL5165, and EL5364 to maintain about the same -3dB bandwidth. 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 160Ω and still retain stability, resulting in only a slight loss of bandwidth with increased closed-loop gain. Supply Voltage Range and Single-Supply Operation RF D1 Feedback Resistor Values The EL5164, EL5165, and EL5364 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 they will operate on dual supplies ranging from ±2.5V to ±5V. With single-supply, the EL5164, EL5165, and EL5364 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 EL5164, EL5165, and EL5364 have an input range which extends to within 2V of either supply. So, for example, on ±5V supplies, the EL5164, EL5165, and EL5364 have an input range which spans ±3V. The output range of the EL5164, EL5165, and EL5364 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. Single-supply output range is larger because of the increased negative swing due to the external pull-down resistor to ground. 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 5.5mA supply current of FN7389.8 October 29, 2007 EL5164, EL5165, EL5364 each EL5164, EL5165, and EL5364 amplifiers. Special circuitry has been incorporated in the EL5164, EL5165, and EL5364 to reduce the variation of output impedance with current output. This results in dG and dP specifications of 0.01% and 0.01°, while driving 150Ω at a gain of 2. Video performance has also been measured with a 500Ω load at a gain of +1. Under these conditions, the EL5164, EL5165, and EL5364 have dG and dP specifications of 0.01% and 0.01°, respectively. Output Drive Capability In spite of their low 5.5mA of supply current, the EL5164, EL5165, and EL5364 are capable of providing a minimum of ±75mA of output current. With a minimum of ±75mA of output drive, the EL5164, EL5165, and EL5364 are capable of driving 50Ω loads to both rails, making it an excellent choice for driving isolation transformers in telecommunications applications. Driving Cables and Capacitive Loads 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 in Equation 2: V OUTMAX PD MAX = ( 2 × V S × I SMAX ) + ( V S – V OUTMAX ) × ---------------------------RL (EQ. 2) where: • VS = Supply voltage • ISMAX = Maximum supply current of 1A • VOUTMAX = Maximum output voltage (required) • RL = Load resistance 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 EL5164, EL5165, and EL5364 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.

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. 0.1µF -5V 375Ω 375Ω VIN FIGURE 24. INVERTING 200mA OUTPUT CURRENT DISTRIBUTION AMPLIFIER Power Dissipation With the high output drive capability of the EL5164, EL5165, and EL5364, it is possible to exceed the +125°C Absolute Maximum junction temperature under certain very high load current conditions. Generally speaking when RL falls below 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 EL5164, EL5165, and EL5364 to remain in the safe operating area. These parameters are calculated in Equation 1: T JMAX = T MAX + ( θ JA × n × PD MAX ) 11 (EQ. 1) FN7389.8 October 29, 2007 EL5164, EL5165, EL5364 375Ω 375Ω 0.1µF +5V IN+ VS+ OUT INVS0.1µF 375Ω -5V 375Ω +5V 0.1µF VIN IN+ VS+ OUT IN- VOUT VS0.1µF -5V FIGURE 25.
