550MHz Differential Twisted-Pair Drivers

The EL5174 and EL5374 are single and triple high

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

inputs can be in either single-ended or differential form but

the outputs are always in differential form.

On the EL5174 and EL5374, 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

EL5173 and EL5373.

The output common mode level for each channel is set by

the associated REF pin, which have a -3dB bandwidth of

over 110MHz. 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 EL5174 is available in an 8-pin SO package and

EL5374 is available in a 28-pin QSOP package. All specified

for operation over the full -40°C to +85°C temperature range.

Features

• Fully differential inputs, outputs, and feedback

• Differential input range ±2.3V

• 550MHz 3dB bandwidth

• 1100V/µs slew rate

• Low distortion at 5MHz

• Single 5V or dual ±5V supplies

• 60mA maximum output current

• Low power - 12.5mA per channel

• Pb-free plus anneal 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
