EL5171, EL5371

250MHz Differential Twisted-Pair Drivers

The EL5171 and EL5371 are single and triple bandwidth

amplifiers with an output in differential form. They are primarily

targeted for applications such as driving twisted-pair lines in

component video applications. The input signal is single-ended

and the outputs are always differential.

On the EL5171 and EL5371, two feedback inputs provide

the user with the ability to set the gain of each device (stable

at minimum gain of one). For a fixed gain of two, please see

EL5170 and EL5370.

The output common mode level for each channel is set by

over 50MHz. Generally, these pins are grounded but can be

tied to any voltage reference.

All outputs are short circuit protected to withstand temporary

overload condition.

The EL5171 and EL5371 are specified for operation over the

full -40°C to +85°C temperature range.

Features

• Fully differential outputs and feedback

• Input range ±2.3V typ.

• 250MHz 3dB bandwidth

• 800V/µs slew rate

• Low distortion at 5MHz

• Single 5V or dual ±5V supplies

• 90mA maximum output current

• Low power - 8mA per channel

• Pb-free available (RoHS compliant)

Applications

• Twisted-pair driver

• Differential line driver

• VGA over twisted-pair

• ADSL/HDSL driver

• Single-ended to differential amplification

• Transmission of analog signals in a noisy environment

NOTE: These Intersil Pb-free plastic packaged products employ

special Pb-free material sets, molding compounds/die attach

materials, and 100% matte tin plate plus anneal (e3 termination

finish, which is 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.
