EL2140C/2141C  
150 MHz Differential Twisted Pair Driver  
Features  
# Fully differential inputs, outputs,  
and feedback  
General Description  
The EL2140C/2141C is a very high bandwidth amplifier whose  
output is in differential form, and is thus primarily targeted for  
applications such as driving twisted pair lines, or any applica-  
tion 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.

55 dB distortion at 3 MHz  
On the EL2141C, two feedback inputs provide the user with the  
ability to set the device gain, (stable at minimum gain of two),  
whereas the EL2140C comes with a fixed gain of two.  
75 dB distortion at 100 kHz

# 50 mA minimum output current  
The output common mode level is set by the reference pin  
b
erally, this pin is grounded, but it can be tied to any voltage  
reference.  
# Output swing (200X load) to  
within 1.5V of supplies  
(14V pk-pk differential)  
(V

), which has a 3 dB bandwidth of over 100 MHz. Gen-  
# Low power-11 mA typical supply  
current  
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 de-  
pend upon input and output signal amplitude, as well as the  
output load impedance. (See distortion data inside.)  
Applications  
# Twisted pair driver  
# Differential line driver  
# VGA over twisted pair  
# ADSL/HDSL driver  
Both outputs (V
