EL5172, EL5372
250MHz Differential Line Receivers
The EL5172 and EL5372 are single and triple high
bandwidth amplifiers designed to extract the difference
signal from noisy environments. They are 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 EL5172 and EL5372 are 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 120MHz.
Generally, this pin is grounded but it can be tied to any
voltage reference.
The output can deliver a maximum of 60mA and is short
circuit protected to withstand a temporary overload
condition.
The EL5172 is available in the 8-pin SO and 8-pin MSOP
packages and the EL5372 in a 24-pin QSOP package. Both
are specified for operation over the full -40C to +85C
temperature range.
Features
Differential input range 2.3V
250MHz 3dB bandwidth
800V/s slew rate
60mA maximum output current
Single 5V or dual 5V supplies
Low power - 5mA to 6mA per channel
Pb-Free plus anneal available (RoHS compliant)
Applications
Twisted-pair receivers
Differential line receivers
VGA over twisted-pair
ADSL/HDSL receivers
Differential to single-ended amplification
Reception of analog signals in a noisy environment

NOTE: Intersil Pb-free plus anneal 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.
