EL5175, EL5375
550MHz Differential Line Receivers
The EL5175 and EL5375 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 EL5175 and EL5375 are stable for a gain of one and
requires two external resistors to set the voltage gain for
each channel.
The output common mode level is set by the reference pin
(V
REF
), which has a -3dB bandwidth of over 450MHz.
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 EL5175 is available in the 8-pin SO and 8-pin MSOP
packages and the EL5375 in the 24-pin QSOP package. All
are specified for operation over the full -40C to +85C
temperature range.

NOTES:
1. 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.
