100MHz Single-Supply Rail-to-Rail Amplifiers

The EL5144 series amplifiers are voltage-feedback, high speed, rail-to-rail amplifiers designed to operate on a single +5V supply. They offer unity gain stability with an unloaded - 3dB bandwidth of 100MHz. The input common-mode voltage range extends from the negative rail to within 1.5V of the positive rail. Driving a 75Ω double terminated coaxial cable, the EL5144 series amplifiers drive to within 150mV of either rail. The 200V/µs slew rate and 0.1/0.1° differential gain/differential phase makes these parts ideal for composite and component video applications. With their voltage feedback architecture, these amplifiers can accept reactive

feedback networks, allowing them to be used in analog filtering applications These amplifiers will source 90mA and sink 65mA.
