EL5191, EL5191A

1GHz Current Feedback Amplifier with Enable

The EL5191 and EL5191A amplifiers are of the current

feedback variety and exhibit a very high bandwidth of 1GHz.

This makes these amplifiers ideal for today’s high speed

video and monitor applications, as well as a number of RF

and IF frequency designs.

With a supply current of just 9mA and the ability to run from

a single supply voltage from 5V to 10V, these amplifiers offer

very high performance for little power consumption.

The EL5191A also incorporates an enable and disable

function to reduce the supply current to 100µA typical per

amplifier. Allowing the

CE

pin to float or applying a low logic

level will enable the amplifier.

The EL5191 is offered in the 5 Ld SOT-23 package and the

industry-standard 8 Ld SOIC package. EL5191A is available

in the industry-standard 8 Ld SOIC package. Both operate

over the industrial temperature range of -40°C to +85°C.

Features

.

• 1GHz -3dB bandwidth

• 9mA supply current

• Single and dual supply operation, from 5V to 10V supply

span

• Fast enable/disable (EL5191A only)

• Available in SOT-23 packages

• High speed, 600MHz product available (EL5192, EL5292,

and EL5392)

• Lower power, 300MHz product available (EL5193,

EL5293, EL5393)

• Pb-Free plus anneal available (RoHS compliant)

Applications

• Video amplifiers

• Cable drivers

• RGB amplifiers

• Test equipment

• Instrumentation

• Current to voltage converters

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
