250MHz Differential Twisted-Pair Drivers
EL5171, EL5371
Features
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.
• Fully differential outputs and feedback
• Input range ±2.3V typ.
• 250MHz 3dB bandwidth
• 800V/µs slew rate
• Low distortion at 5MHz
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.
• Single 5V or dual ±5V supplies
• 90mA maximum output current
• Low power - 8mA per channel
• Pb-free available (RoHS compliant)
The output common mode level for each channel is set by the
associated V
pin, which have a -3dB bandwidth of over
REF
50MHz. Generally, these pins are grounded but can be tied to
any voltage reference.
Applications
• Twisted-pair driver
All outputs are short circuit protected to withstand temporary
overload condition.
• Differential line driver
• VGA over twisted-pair
The EL5171 and EL5371 are specified for operation over the
full -40°C to +85°C temperature range.
• ADSL/HDSL driver
• Single-ended to differential amplification
• Transmission of analog signals in a noisy environment
