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
The EL2142C is stable for a gain of one and requires two exter-
nal resistors to set the voltage gain
The output common mode level is set by the reference pin
(V
REF
) which has a
b
3 dB bandwidth of over 100 MHz Gen-
erally this pin is grounded but it can be tied to any voltage
reference
The output can deliver a minimum of
g
50 mA and is short
circuit protected to withstand a temporary overload condition
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
