700MHz Differential Twisted-Pair Drivers
EL5178, EL5378
The EL5178 and EL5378 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 EL5178 and EL5378, two feedback inputs provide the
user with the ability to set the gain of each device (stable at
minimum gain of 2).
The output common mode level for each channel is set by the
associated REF pin, which has 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 EL5178 is available in 8 Ld MSOP and SOIC packages and
EL5378 is available in a 28 Ld QSOP package. All are 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
• 700MHz 3dB bandwidth
• 1000V/µs slew rate
• Low distortion at 5MHz and 20MHz
• Single 5V or dual ±5V supplies
• 60mA maximum output current
• Low power - 12.5mA 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
