FN7048.1
150MHz Differential Twisted Pair Driver
Features
The EL2141 is a very high bandwidth amplifier whose output
is in differential form, and is thus primarily targeted for appli-
cations 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.
• Fully differential inputs, outputs, and feedback
• Differential input range ±2.3V
• 150MHz 3dB bandwidth
• 800V/µs slew rate
• -55dB distortion at 3MHz
On the EL2141, two feedback inputs provide the user with
the ability to set the device gain, (stable at minimum gain of
two).
• -75dB distortion at 100kHz
• ±5V supplies or +6V single supply
• 50mA minimum output current
• Output swing (200Ω load) to within 1.5V of supplies
The output common mode level is set by the reference pin
(V
), which has a -3dB bandwidth of over 100MHz. Gen-
REF
erally, this pin is grounded, but it can be tied to any voltage
reference.

PKPK
The transmission of ADSL/HDSL signals requires very low
distortion amplification, so this amplifier was designed with
this as a primary goal. The actual signal distortion levels
depend upon input and output signal amplitude, as well as
the output load impedance. (See distortion data inside.)
• Low power-11mA typical supply current
• Pb-free available (RoHS compliant)
Applications
Both outputs (V ) are short circuit protected to
withstand temporary overload condition.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are 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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
