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
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 Ld SOIC and 8 Ld MSOP
packages and the EL5372 in a 24 Ld QSOP package. Both
are specified for operation over the full -40°C to +85°C
temperature range.
