250MHz Differential Twisted-Pair Driver
EL5176
The EL5176 is a high bandwidth amplifier with an output in
differential form. It is primarily targeted for applications such
as driving twisted-pair lines or any application where common
mode injection is likely to occur. The input signal can be in
either single-ended or differential form but the output is
always in differential form.
On the EL5176, two feedback inputs provide the user with the
ability to set the device gain (stable at minimum gain of one).
The output common mode level is set by the reference pin
(REF), which has a -3dB bandwidth of over 50MHz. Generally,
this pin is grounded but it can be tied to any voltage reference.
Both outputs (OUT+, OUT-) are short-circuit protected to
withstand temporary overload condition.
The EL5176 is available in the 10 Ld MSOP package and is
specified for operation over the full -40°C to +85°C
temperature range.
See also EL5171 (EL5176 in 8 Ld MSOP).
Features
• Fully differential inputs, outputs, and feedback
• 250MHz 3dB bandwidth
• 800V/µs slew rate
• Low distortion at 20MHz
• Single 5V or dual ±5V supplies
• 40mA maximum output current
• Low power - 8mA typical supply current
• Pb-free (RoHS compliant)
Applications
• Twisted-pair drivers
• Differential line drivers
• VGA over twisted-pair
• ADSL/HDSL drivers
• Single-ended to differential amplification
• Transmission of analog signals in a noisy environment
