9 EL2073C 200mhz unity-gain stable operational amplifier e l 2 0 7 3 c applications information product description the EL2073C is a wideband monolithic operational amplifier built on a high-speed complementary bipolar process. the EL2073C uses a classical voltage-feedback topology which allows it to be used in a variety of appli- cations where current-feedback amplifiers are not appropriate because of restrictions placed upon the feed- back element used with the amplifier. the conventional topology of the EL2073C allows, for example, a capaci- tor to be placed in the feedback path, making it an excellent choice for applications such as active filters, sample-and-holds, or integrators. similarly, because of the ability to use diodes in the feedback network, the EL2073C is an excellent choice for applications such as log amplifiers. the EL2073C also has excellent dc specifications: 200v, v os , 2a i b , 0.1a i os , and 90db of cmrr. these specifications allow the EL2073C to be used in dc-sensitive applications such as difference amplifiers. furthermore, the current noise of the EL2073C is only 3.2 pa/hz, making it an excellent choice for high-sensi- tivity transimpedance amplifier configurations. gain-bandwidth product the EL2073C has a gain-bandwidth product of 200mhz. for gains greater than 4, its closed-loop -3db bandwidth is approximately equal to the gain-bandwidth product divided by the noise gain of the circuit. for gains less than 4, higher-order poles in the amplifier's transfer function contribute to even higher closed loop bandwidths. for example, the EL2073C has a -3db bandwidth of 400mhz at a gain of +1, dropping to 200mhz at a gain of +2. it is important to note that the EL2073C has been designed so that this ?extra? band- width in low-gain applications does not come at the expense of stability. as seen in the typical performance curves, the EL2073C in a gain of +1 only exhibits 1db of peaking with a 100 w load. video performance an industry-standard method of measuring the video distortion of a component such as the EL2073C is to measure the amount of differential gain (dg) and differ- ential phase (dp) that it introduces. to make these measurements, a 0.286v pp (40 ire) signal is applied to the device with 0v dc offset (0 ire) at either 3.58mhz for ntsc, 4.43mhz for pal, or 30mhz for hdtv. a second measurement is then made at 0.714v dc offset (100 ire). differential gain is a measure of the change in amplitude of the sine wave, and is measured in per- cent. differential phase is a measure of the change in phase, and is measured in degrees. for signal transmission and distribution, a back-termi- nated cable (75 w in series at the drive end, and 75 w to ground at the receiving end) is preferred since the impedance match at both ends will absorb any reflec- tions. however, when double termination is used, the received signal is halved; therefore a gain of 2 configu- ration is typically used to compensate for the attenuation. the EL2073C has been designed to be among the best video amplifiers in the marketplace today. it has been thoroughly characterized for video performance in the topology described above, and the results have been included as minimum dg and dp specifications and as typical performance curves. in a gain of +2, driving 150 w , with standard video test levels at the input, the EL2073C exhibits dg and dp of only 0.01% and 0.015 at ntsc and pal. because dg and dp vary with differ- ent dc offsets, the superior video performance of the EL2073C has been characterized over the entire dc off- set range from -0.714v to +0.714v. for more information, refer to the curves of dg and dp vs dc input offset. the excellent output drive capability of the EL2073C allows it to drive up to 4 back-terminated loads with excellent video performance. with 4 150 w loads, dg and dp are only 0.15% and 0.08 at ntsc and pal. for more information, refer to the curves for video perfor- mance vs number of 150 w loads. output drive capability the EL2073C has been optimized to drive 50 w and 75 w loads. it can easily drive 6v pp into a 50 w load. this high output drive capability makes the EL2073C an ideal choice for rf, if and video applications. furthermore,
10 EL2073C 200mhz unity-gain stable operational amplifier e l 2 0 7 3 c the current drive of the EL2073C remains a minimum of 50ma at low temperatures. the EL2073C is current- limited at the output, allowing it to withstand momen- tary shorts to ground. however, power dissipation with the output shorted can be in excess of the power-dissipa- tion capabilities of the package. capacitive loads although the EL2073C has been optimized to drive resistive loads as low as 50 w , capacitive loads will decrease the amplifier's phase margin which may result in peaking, overshoot, and possible oscillation. for opti- mum ac performance, capacitive loads should be reduced as much as possible or isolated via a series out- put resistor. coax lines can be driven, as long as they are terminated with their characteristic impedance. when properly terminated, the capacitance of coaxial cable will not add to the capacitive load seen by the amplifier. capacitive loads greater than 10pf should be buffered with a series resistor (rs) to isolate the load capacitance from the amplifier output. a curve of recommended rs vs cload has been included for reference. values of rs were chosen to maximize resulting bandwidth without peaking. printed-circuit layout as with any high-frequency device, good pcb layout is necessary for optimum performance. ground-plane con- struction is highly recommended, as is good power supply bypassing. a 1f?10f tantalum capacitor is recommended in parallel with a 0.01f ceramic capaci- tor. all lead lengths should be as short as possible, and all bypass capacitors should be as close to the device pins as possible. parasitic capacitances should be kept to an absolute minimum at both inputs and at the output. resistor values should be kept under 1000 w to 2000 w because of the rc time constants associated with the parasitic capacitance. metal-film and carbon resistors are both acceptable, use of wire-wound resistors is not recommended because of parasitic inductance. simi- larly, capacitors should be low-inductance for best performance. if possible, solder the EL2073C directly to the pc board without a socket. even high quality sockets add parasitic capacitance and inductance which can potentially degrade performance. because of the degra- dation of ac performance due to parasitics, the use of surface-mount components (resistors, capacitors, etc.) is also recommended.
