EL5100, EL5101, EL5300 ® Data Sheet September 22, 2004 200MHz Slew Enhanced VFA Features The EL5100, EL5101, and EL5300 represent high-speed voltage feedback amplifiers based on the current feedback amplifier architecture. This gives the typical high slew rate benefits of a CFA family along with the stability and ease of use associated with the VFA type architecture. This family is available in single, dual, and triple versions, with 200MHz, 400MHz, and 700MHz versions. This family operates on single 5V or ±5V supplies from minimum supply current. The EL5100 and EL5300 also feature an output enable function, which can be used to put the output in to a high-impedance mode. This enables the outputs of multiple amplifiers to be tied together for use in multiplexing applications. • Pb-free available as an option Ordering Information • AVOL = 1000 PART NUMBER FN7330.1 • Specified for 5V or ±5V applications • Power-down to 17µA/amplifier • -3dB bandwidth = 200MHz • ±0.1dB bandwidth = 20MHz • Low supply current = 2.5mA • Slew rate = 2200V/µs • Low offset voltage = 4mV max • Output current = 100mA • Diff gain/phase = 0.08%/0.1° PACKAGE TAPE & REEL PKG.

VIDEO- In the past when the bandwidth of the operational amplifier ended at a few hundred kHz even at few MHz, the powersupply bypass was not a very critical issue, since a 0.1µF capacitor “did the job”, but today’s amplifiers could have bandwidth, what used to be reserved for microwave circuits not to long time ago. Therefore that high bandwidth amplifiers require the same respect what we reserve for microwave circuits. Particularly the power supply bypass and the pcb-layout could very heavily influence the performance of a modern high bandwidth amplifiers. It could happen above a few MHz, but it will happen above 100MHz, that the capacitor will behave like an inductor. The test result is shown on Figure 30. By selecting a different value for C1, we could reduce the effect, created by C3 R3 and get flat response from 16Hz 10 FN7330.1 EL5100, EL5101, EL5300 CAPACITIVE Z INDUCTIVE The reason for that is the very small but not zero value serial inductance of the capacitor. Ci Above its serial resonance C2* the ideal capacitance of C2 is a short, the Tantalum capacitor for high frequencies is not effective, the left over is C1 capacitor and L1 + L2 inductors, we get a parallel tank circuit, which is at it’s resonance a high impedance path and do not carry any high frequency current, it does not work as bypass at all! The impedance of a parallel tank circuit at resonance is dependent from it’s Q. High Q high impedance. Li F F RES FIGURE 31. The capacitor will behave as a capacitor up to its resonance frequency, above the resonance frequency it will behave as an inductor. Just 1nHy inductance serial with 1nF capacitance will have serial resonance at: 1 F= 2π L × C C = 1nF, L = 1nHy, F = 159 MHz The Q of a parallel tank circuit could be reduced by bypassing it with a resistor, or adding a resistor in serial to one of the reactive components. Since the bypassing would short the DC supply we do have to go to add resistor in serial to the reactive component, we will ad a resistor serial with the inductor. (See Figure 33.) C3 Z R3 = 0 L3 R3 = 3 R3 And an other 1nHy is very easy to get together with the inductance of traces on the pcb, and therefore you could encounter resonances from ca 50MHz and above anywhere. So if the amplifier has a bandwidth of a few hundred MHz, the proper power supply by-pass could become a serious if not difficult task. Intuitively, you would use capacitors value 0.1µF parallel with a few µF tantalum, and to cure the effect of it’s serial resonance put a smaller one parallel to it. The result will surprise to you, because you will get even something worse than without the small capacitor. C2 1n 1n C3 0.1µF 22µF 0.1µF = L1 < L2 F RES FIGURE 33.
