wide -3dB bandwidth of 400MHz and a low supply current of 9mA per amplifier. The EL5396A works 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. This combination of high bandwidth and low power, together with aggressive pricing make the EL5396A the ideal choice for many low-power/high-bandwidth applications such as portable, handheld, or battery-powered equipment. temperature and process, external resistor should not be used to adjust the gain settings. 400 400 ININ+ + FIGURE 1. AV = +2 400 400 For varying bandwidth and higher gains, consider the EL5191 with 1GHz on a 9mA supply current or the EL5193 with 300MHz on a 4mA supply current. Versions include single, dual, and triple amp packages with 5-pin SOT23, 16pin QSOP, and 8-pin or 16-pin SO 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. Disable/Power-Down The EL5396A amplifier can be disabled placing its output in a high impedance state. When disabled, the amplifier supply current is reduced to < 150µA. The EL5396A 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 EL5396A 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 EL5396A to be enabled by tying CE to ground, even in 5V single supply applications. The CE pin can be driven from CMOS outputs. Gain Setting The EL5396A is built with internal feedback and gain resistors. The internal feedback resistors have equal value; as a result, the amplifier can be configured into gain of +1, -1, and +2 without any external resistors. Figure 1 shows the amplifier in gain of +2 configuration. The gain error is ±2% maximum. Figure 2 shows the amplifier in gain of -1 configuration. For gain of +1, IN+ and IN- should be connected together as shown in Figure 3. This configuration avoids the effects of any parasitic capacitance on the IN- pin. Since the internal feedback and gain resistors change with 12 ININ+ + FIGURE 2. AV = -1 400 IN- 400 + IN+ FIGURE 3. AV = +1 Supply Voltage Range and Single-Supply Operation The EL5396A has been designed to operate with supply voltages having a span of greater than or equal to 5V and less than 11V. In practical terms, this means that the EL5396A will operate on dual supplies ranging from ±2.5V to ±5V. With single-supply, the EL5396A 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 EL5396A has an input range which extends to within 2V of either supply. So, for example, on ±5V supplies, the EL5396A has an input range which spans ±3V. The output range of the EL5396A 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. Figure 4 shows EL5396A an AC-coupled, gain of +2, +5V single supply circuit configuration. 400 +5 Current Limiting 400 + +5 0.1µF 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. VOUT The EL5396A has 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. 1k Power Dissipation 0.1µF VIN 1k FIGURE 4. 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 9mA supply current of each EL5396A amplifier. Special circuitry has been incorporated in the EL5396A to reduce the variation of output impedance with current output. This results in dG and dP specifications of 0.0035% and 0.04°, 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 EL5396A has dG and dP specifications of 0.03% and 0.05°, respectively. With the high output drive capability of the EL5396A, 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 EL5396A 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: Output Drive Capability In spite of its low 9mA of supply current, the EL5396A is capable of providing a minimum of ±95mA of output current. With a minimum of ±95mA of output drive. 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 EL5396A from the cable and allow extensive capacitive drive. However, other applications may have high VS = Supply voltage ISMAX = Maximum supply current VOUTMAX = Maximum output voltage (required) RL = Load resistance All Intersil U.S. products are manufactured, assembled and tested utilizing ISO9000 quality systems.
