, EL5260,

EL5261 and EL5360 are a current feedback amplifier with a bandwidth of 200MHz, with a working current of only 0.75 mAh. This makes these amplifiers ideal for today's high -speed video and monitor applications. These amplifiers can run from 5 to 10 volt voltage, which is an ideal choice for handheld, portable or battery power supply equipment. EL5160, EL5260, and EL5360 also have enable and disable functions, which can reduce the power supply current to the typical values of each amplifier of 14 microan. The CE is allowed to sell the corresponding amplifiers with low logic levels. EL5160 has 6 LD SOT-23 and 8 LD SOIC packaging, 5 LD SOT-23 packaging EL5161, 10 LD MSOP packaged EL5260, 8 LD SOIC packaging EL5261, 16 LD SOIC and QSOP EL5360 in the package. All equipment runs within the industrial temperature range of -40 ° C to+85 ° C.

Product description

EL5160, EL5161, EL5260, EL5261, and EL5360 are low -power current feedback amplifiers, providing 200MHz width 3DB bandwidth and low power currents of each amplifier 0.75mA. EL5160, EL5161, EL5260, EL5261, and EL5360 working power supply voltage ranges from a single 5V to 10V, and they can also swing within the 1V range of the output power supply. Due to its current feedback topology, EL5160, EL5161, EL5260, EL5261, and EL5360 do not have the normal gain band widely associated with the voltage feedback computing amplifier. Instead, with the increase of closed-loop gain, their -3DB bandwidth remains relatively constant. The combination of high bandwidth and low power consumption, coupled with positive pricing, makes EL5160, EL5161, EL5260, EL5261, and EL5360 the ideal choice for many low power/high bandwidth applications (such as portable, handheld or battery power equipment).

Power bypass and printing circuit board layout

Like any high -frequency device, a good printing circuit board layout is a necessary condition for gaining the best performance. Low impedance ground plane structure is essential. It is recommended to use the surface installation parts, but if you use a leading part, the wire length should be as short as possible. It must be completely bypassed the power of the power to reduce the risk of oscillation. The combination of 4.7 μF 器 capacitor and 0.01 μF capacitors work well when placed at each power supply.

In order to obtain good communication performance, parasitic capacitors should be kept at the minimum value, especially in the inverter input end. (See the Capacitors in the Invasion " section)) Even if the grounding plane structure is used
