EL2141

150MHz Differential Twisted Pair Driver

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.

On the EL2141, two feedback inputs provide the user with

the ability to set the device gain, (stable at minimum gain of

two).

The output common mode level is set by the reference pin

erally, this pin is grounded, but it can be tied to any voltage

reference.

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.)

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.
