EL5308IU

DATASHEET EL5108, EL5308 FN7358 Rev 8.00 August 11, 2015 450MHz Fixed Gain Amplifiers with Enable The EL5108 and EL5308 are fixed gain amplifiers with a bandwidth of 450MHz. This makes these amplifiers ideal for today’s high speed video and monitor applications. They 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. Features • Pb-free available (RoHS compliant) • Gain selectable (+1, -1, +2) • 450MHz -3dB BW (AV = -1, +1, +2) • 3.5mA supply current per amplifier The EL5108 and EL5308 also incorporate an enable and disable function to reduce the supply current to 25µA typical per amplifier. Allowing the CE pin to float or applying a low logic level will enable the amplifier. • Single and dual supply operation, from 5V to 12V • Available in SOT-23 packages • 350MHz, 1.5mA product available (EL5106 and EL5306) The EL5108 is offered in the 6 Ld SOT-23 and the industrystandard 8 Ld SOIC packages and the EL5308 is available in the 16 Ld SOIC and 16 Ld QSOP packages. All operate over the industrial temperature range of -40°C to +85°C. Applications • Battery powered equipment • Handheld, portable devices • Video amplifiers • Cable drivers • RGB amplifiers Ordering Information PART NUMBER PART MARKING PACKAGE PKG.

They work with supply voltages ranging from a single 5V to 10V and they are also capable of swinging to within 1.2V of either supply on the output. These combinations of high bandwidth, low power, and high slew rate make the EL5108 and EL5308 the ideal choice for many lowpower/high-bandwidth applications such as portable, handheld, or battery-powered equipment. For varying bandwidth and higher gains, consider the EL5166 with 1GHz on a 9mA supply current or the EL5164 with 600MHz on a 3.5mA supply current. Versions include single, dual, and triple amp packages with 6 Ld SOT-23, 16 Ld QSOP, and 8 Ld SOIC or 16 Ld SOIC outlines. 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 EL5108 and EL5308 amplifiers can be disabled and placing their outputs in a high impedance state. When disabled, the amplifier supply current is reduced to
