The EL5160, EL5161, EL5260, EL5261, and EL5360 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 EL5160, EL5161, EL5260, EL5261, and EL5360 do not have the normal gainbandwidth product associated with voltage-feedback operational amplifiers. Instead, their -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 EL5160, EL5161, EL5260, EL5261, and EL5360 ideal choices for many lowpower/high-bandwidth applications such as portable, handheld, or battery-powered equipment. inductance and capacitance which will result in additional 8 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 peaking and overshoot. FN7387.8 September 8, 2005 EL5160, EL5161, EL5260, EL5261, EL5360 Disable/Power-Down The EL5160 amplifier can be disabled placing its output in a high impedance state. When disabled, the amplifier supply current is reduced to < 15µA. The EL5160 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 EL5160 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 EL5160 to be enabled by tying CE to ground, even in 5V single supply applications. The CE pin can be driven from CMOS outputs. 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 EL5160, EL5161, EL5260, EL5261, and EL5360 have been optimized with a TBDΩ 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. Feedback Resistor Values The EL5160, EL5161, EL5260, EL5261, and EL5360 have been designed and specified at a gain of +2 with RF approximately 806Ω. This value of feedback resistor gives 200MHz of -3dB bandwidth at AV = 2 with TBDdB of peaking. With AV = -2, an RF of approximately TBDΩ gives 200MHz of bandwidth with 1dB of peaking. Since the EL5160, EL5161, EL5260, EL5261, and EL5360 are currentfeedback 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 EL5160, EL5161, EL5260, EL5261, and EL5360 are current-feedback amplifiers, their gainbandwidth product is not a constant for different closed-loop gains. This feature actually allows the EL5160, EL5161, EL5260, EL5261, and EL5360 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 9 to reduce the value of RF below the specified TBDΩ 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 EL5160, EL5161, EL5260, EL5261, and EL5360 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 EL5160, EL5161, EL5260, EL5261, and EL5360 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 EL5160, EL5161, EL5260, EL5261, and EL5360 have an input range which extends to within 2V of either supply. So, for example, on +5V supplies, the EL5160, EL5161, EL5260, EL5261, and EL5360 have an input range which spans ±3V. The output range of the EL5160, EL5161, EL5260, EL5261, and EL5360 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 1mA supply current of each EL5160, EL5161, EL5260, EL5261, and EL5360 amplifier. Special circuitry has been incorporated in the EL5160, EL5161, EL5260, EL5261, and EL5360 to reduce the variation of output impedance with current output. This results in dG and dP specifications of 0.1% and 0.1°, 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 EL5160 has dG and dP specifications of 0.1% and 0.1°. Output Drive Capability In spite of their low 1mA of supply current, the EL5160, EL5161, EL5260, EL5261, and EL5360 are capable of providing a minimum of ±50mA of output current. With a minimum of ±50mA of output drive, the EL5160 is capable of driving 50Ω loads to both rails, making it an excellent choice for driving isolation transformers in telecommunications applications. FN7387.8 September 8, 2005 EL5160, EL5161, EL5260, EL5261, EL5360 Driving Cables and Capacitive Loads where: 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 EL5160, EL5161, EL5260, EL5261, and EL5360 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. • VS = Supply voltage • ISMAX = Maximum supply current of 0.75mA • VOUTMAX = Maximum output voltage (required) • RL = Load resistance Typical Application Circuits 0.1µF +5V IN+ VS+ IN- VS- -5V OUT 0.1µF 500Ω Current Limiting The EL5160, EL5161, EL5260, EL5261, and EL5360 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. 0.1µF +5V IN+ VS+ IN- VS- Power Dissipation With the high output drive capability of the EL5160, EL5161, EL5260, EL5261, and EL5360, 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 EL5160, EL5161, EL5260, EL5261, and EL5360 to remain in the safe operating area.
