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 (VREF), 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 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.
