| (R) EL8108 Data Sheet January 29, 2008 FN7417.2 Video Distribution Amplifier The EL8108 is a dual current feedback operational amplifier designed for video distribution solutions. This device features a high drive capability of 450mA while consuming only 5mA of supply current per amplifier and operating from a single 5V to 12V supply. The EL8108 is available in the industry standard 8 Ld SOIC as well as the thermally-enhanced 16 Ld QFN package. Both are specified for operation over the full -40C to +85C temperature range. The EL8108 has control pins C0 and C1 for controlling the bias and enable/disable of the outputs. The EL8108 is ideal for driving multiple video loads while maintaining linearity. Features * Drives up to 450mA from a +12V supply * 20VP-P differential output drive into 100 * -85dBc typical driver output distortion at full output at 150kHz * -70dBc typical driver output distortion at 3.75MHz * Low quiescent current of 5mA per amplifier * 300MHz bandwidth * Pb-free available (RoHS compliant) Applications * Video distribution amplifiers TABLE 1.

PACKAGE POWER DISSIPATION vs AMBIENT TEMPERATURE FIGURE 39. PACKAGE POWER DISSIPATION vs AMBIENT TEMPERATURE Applications Information Product Description The EL8108 is a dual current feedback operational amplifier designed for video distribution solutions. It is a dual current mode feedback amplifier with low distortion while drawing moderately low supply current. It is built using Intersil's proprietary complimentary bipolar process and is offered in industry standard pinouts. Due to the current feedback architecture, the EL8108 closed-loop 3dB bandwidth is dependent on the value of the feedback resistor. First the desired bandwidth is selected by choosing the feedback resistor, RF, and then the gain is set by picking the gain resistor, RG. The curves at the beginning of the "Typical Performance Curves" on page 4 show the effect of varying both RF and RG. The 3dB bandwidth is somewhat dependent on the power supply voltage. 10 Power Supply Bypassing and Printed Circuit Board Layout As with any high frequency device, good printed circuit board layout is necessary for optimum performance. Ground plane construction is highly recommended. Lead lengths should be as short as possible, below 1/4". The power supply pins must be well bypassed to reduce the risk of oscillation. A 4.7F tantalum capacitor in parallel with a 0.1F ceramic capacitor is adequate for each supply pin. For good AC performance, parasitic capacitances should be kept to a minimum, especially at the inverting input. This implies keeping the ground plane away from this pin. Carbon resistors are acceptable, while use of wire-wound resistors should not be used because of their parasitic inductance. Similarly, capacitors should be low inductance for best performance. FN7417.2 January 29, 2008 EL8108 Capacitance at the Inverting Input Due to the topology of the current feedback amplifier, stray capacitance at the inverting input will affect the AC and transient performance of the EL8108 when operating in the non-inverting configuration. In the inverting gain mode, added capacitance at the inverting input has little effect since this point is at a virtual ground and stray capacitance is therefore not "seen" by the amplifier. Single Supply Operation If a single supply is desired, values from +5V to +12V can be used as long as the input common mode range is not exceeded. When using a single supply, be sure to either: 1. DC bias the inputs at an appropriate common mode voltage and AC couple the signal, or 2. Ensure the driving signal is within the common mode range of the EL8108. Driving Cables and Capacitive Loads The EL8108 was designed with driving multiple coaxial cables in mind. With 450mA of output drive and low output impedance, driving six, 75 double terminated coaxial cables to 11V with one EL8108 is practical. 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 EL8108 from the capacitive cable and allow extensive capacitive drive. Other applications may have high capacitive loads without termination resistors. In these applications, an additional small value (5 to 50) resistor in series with the output will eliminate most peaking. The following schematic show the EL8108 driving 6 double terminated cables, each an average length of 50 ft. Feedback Resistor Values The EL8108 has been designed and specified with RF = 500 for AV = +2. This value of feedback resistor yields extremely flat frequency response with little to no peaking out to 200MHz. As is the case with all current feedback amplifiers, wider bandwidth, at the expense of slight peaking, can be obtained by reducing the value of the feedback resistor. Inversely, larger values of feedback resistor will cause rolloff to occur at a lower frequency. See "Typical Performance Curves" beginning on page 4, which show 3dB bandwidth and peaking vs frequency for various feedback resistors and various supply voltages. Bandwidth vs Temperature Whereas many amplifier's supply current and consequently 3dB bandwidth drop off at high temperature, the EL8108 was designed to have little supply current variations with temperature. An immediate benefit from this is that the 3dB bandwidth does not drop off drastically with temperature. Supply Voltage Range The EL8108 has been designed to operate with supply voltages from 2.5V to 6V. Optimum bandwidth, slew rate, and video characteristics are obtained at higher supply voltages. However, at 2.5V supplies, the 3dB bandwidth at AV = +5 is a respectable 200MHz. 11 FN7417.2 January 29, 2008 EL8108 +5V EL8108 -5V 750 750 All Intersil U.S. products are manufactured, assembled and tested utilizing ISO9000 quality systems.
