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

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.

Features

• Differential input range ±2.3V

• 250MHz 3dB bandwidth

• 800V/µs slew rate

• 60mA maximum output current

• Single 5V or dual ±5V supplies

• Low power - 5mA to 6mA per channel

• Pb-free 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
