EL2142C
Differential Line Receiver
Features
General Description
The EL2142C 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 sig-
nals from twisted pair lines, or any application where common
mode noise injection is likely to occur.
g
# Differential input range 2.3V
# 150 MHz 3 dB bandwidth
# 400 V/ms slewrate
g
#
5V supplies or single supply
# 50 mA minimum output current
# Output swing (100X load) to
within 1.5V of supplies
The EL2142C is stable for a gain of one, and requires two exter-
nal resistors to set the voltage gain.
b
# Low power 11 mA typical
The output common mode level is set by the reference pin
b
), which has a 3 dB bandwidth of over 100 MHz. Gen-
erally, this pin is grounded, but it can be tied to any voltage
reference.

Applications
# Twisted pair receiver
# Differential line receiver
# VGA over twisted pair
# ADSL/HDSL receiver

The output can deliver a minimum of 50 mA and is short
circuit protected to withstand a temporary overload condition.
# Differential to single ended
amplification.
