The EL5177 is a high bandwidth amplifier with an output in differential form. It is primarily targeted for applications such as driving twisted-pair lines or any application where common mode injection is likely to occur. The input signal can be in either single-ended or differential form but the output is always in differential form. On the EL5177, two feedback inputs provide the user with the ability to set the device gain (stable at a minimum gain of 1). The output common mode level is set by the reference pin (REF), which has a -3dB bandwidth of 110MHz. Generally, this pin is grounded but it can be tied to any voltage reference. Both outputs (OUT+, OUT-) are short circuit protected to withstand temporary overload condition. The EL5177 is available in the 10 Ld MSOP package and is specified for operation over the full -40°C to +85°C temperature range. See also EL5174 (EL5177 in 8 Ld MSOP).
