NS ESIG WD E N FOR 108 DED 5 MEN 5106, EL M O C L E E R SEE NOT ® Data Sheet August 3, 2005 Single 200MHz Fixed Gain Amplifier with Enable The EL5197 and EL5197A are fixed gain amplifiers with a bandwidth of 200MHz, making these amplifiers ideal for today’s high speed video and monitor applications. These amplifiers feature internal gain setting resistors and can be configured in a gain of +1, -1 or +2. The same bandwidth is seen in both gain-of-1 and gain-of-2 applications. With a supply current of just 4mA and the ability to run from a single supply voltage from 5V to 10V, these amplifiers are also ideal for hand held, portable or battery powered equipment. The EL5197A 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 EL5197 is offered in the 5-pin SOT-23 package and the EL5197A is available in the 6-pin SOT-23 as well as the industry-standard 8-pin SO packages. Both operate over the industrial temperature range of -40°C to +85°C.

current of 4mA. The EL5197 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 EL5197 the ideal choice for many low-power/highbandwidth applications such as portable, handheld, or battery-powered equipment. 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 SOT-23, 16pin QSOP, and 8-pin or 16-pin SO outlines. temperature and process, external resistor should not be used to adjust the gain settings. 400 400 - IN- + IN+ FIGURE 1. AV = +2 400 400 IN- IN+ + FIGURE 2. AV = -1 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 EL5197A amplifier can be disabled placing its output in a high impedance state. When disabled, the amplifier supply current is reduced to < 150µA. The EL5197A 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 EL5197A 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 EL5197A 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 EL5197A 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 12 400 IN- 400 + IN+ FIGURE 3. AV = +1 Supply Voltage Range and Single-Supply Operation The EL5197 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 EL5197 will operate on dual supplies ranging from ±2.5V to ±5V. With single-supply, the EL5197 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 EL5197 has an input range which extends to within 2V of either supply. So, for example, on ±5V supplies, the EL5197 has an input range which spans ±3V. The output range of the EL5197 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 EL5197, EL5197A external pull-down resistor to ground. Figure 4 shows an ACcoupled, gain of +2, +5V single supply circuit configuration. 400 +5 decouple the EL5197 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. Current Limiting 400 +5 0.1µF + VOUT 1k The EL5197 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. 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 4mA supply current of each EL5197 amplifier. Special circuitry has been incorporated in the EL5197 to reduce the variation of output impedance with current output. This results in dG and dP specifications of 0.03% 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 EL5197 has dG and dP specifications of 0.03% and 0.04°, respectively. With the high output drive capability of the EL5197, 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 EL5197 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 Output Drive Capability In spite of its low 4mA of supply current, the EL5197 is capable of providing a minimum of ±95mA of output current with a minimum of ±95mA of output drive. where: VS = Supply voltage Driving Cables and Capacitive Loads ISMAX = Maximum supply current of 1A When used as a cable driver, double termination is always recommended for reflection-free performance. For those applications, the back-termination series resistor will VOUTMAX = Maximum output voltage (required) RL = Load resistance All Intersil U.S. products are manufactured, assembled and tested utilizing ISO9000 quality systems.
