250MHz Differential Twisted-Pair Driver
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).

(Note)
*Add “-T7” or “-T13” suffix for tape and reel. Please refer to TB347
for details on reel specifications.
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.

... If the input common mode or differential mode signal is outside the above-specified ranges, it will cause the output signal to become distorted. The output of the EL5176 can swing from -3.8V to +3.9V at 1kΩ differential load at ±5V supply. As the load resistance becomes lower, the output swing is reduced. ...

... Again, a small series resistor at the output can help to reduce peaking. Disable/Power-Down The EL5176 can be disabled and its outputs placed in a high impedance state. The turn-off time is about 0.95µs and the turn-on time is about 215ns. When disabled, the amplifier's supply current is reduced to 1.7µA for I typically, thereby effectively eliminating the power consumption ...
