EL2142
Data Sheet February 11, 2005
Differential Line Receiver
The EL2142 is a very high bandwidth amplifier designed to
extract the difference signal from noisy environments, and is
thus primarily targeted for applications such as receiving
signals from twisted pair lines, or any application where
common mode noise injection is likely to occur.
The EL2142 is stable for a gain of one, and requires two
external resistors to set the voltage gain.
The output common mode level is set by the reference pin
(V
REF
), which has a -3dB bandwidth of over 100MHz.
Generally, this pin is grounded, but it can be tied to any
voltage reference.
The output can deliver a minimum of ±50mA and is short
circuit protected to withstand a temporary overload
condition.
Features
• Differential input range ±2.3V
• 150MHz 3dB bandwidth
• 400V/µs slewrate
• ±5V supplies or single supply
• 50mA minimum output current
• Output swing (100Ω load) to within 1.5V of supplies
• Low power-11mA typical supply current
• Pb-free available (RoHS compliant)
Applications
• Twisted pair receiver
• Differential line receiver
• VGA over twisted pair
• ADSL/HDSL receiver
• Differential to single ended amplification.
• Reception of analog signals in a noisy environment.

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.
