Description

The EL5144 series amplifiers are voltage-feedback, high speed, rail-torail amplifiers designed to operate on a single +5V supply. They offer unity gain stability with an unloaded -3dB bandwidth of 100MHz. The input commonmode 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.

The EL5146 and EL5246 have a power-savings disable feature. Applying a standard TTL low logic level to the CE (Chip Enable) pin reduces the supply current to 2.6µA within 10ns. Turn-on time is 500ns, allowing true break-beforemake conditions for multiplexing applications. Allowing the CE pin to float or applying a high logic level will enable the amplifier.

For applications where board space is critical, singles are offered in a 5-pin SOT-23 package, duals in 8- and 10-pin MSOP packages, and quads in a 16-pin QSOP package. Singles, duals, and quads are also available in industrystandard pinouts in SO and PDIP packages. All parts operate over the industrial temperature range of -40°C to +85°C.
