The  EL2141( EL2141CSZ-T7 ) is a very high bandwidth amplifier whose output is in differential form, and is thus 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 EL2141, two feedback inputs provide the user with the ability to set the device gain, (stable at minimum gain of two).The output common mode level is set by the reference pin (VREF), which has a -3dB bandwidth of over 100MHz. Generally, this pin is grounded, but it can be tied to any voltage reference.The transmission of ADSL/HDSL signals requires very low distortion amplification, so this amplifier was designed with this as a primary goal. The actual signal distortion levels depend upon input and output signal amplitude, as well as the output load impedance. (See distortion data inside.)Both outputs (VOUT, VOUTB) are short circuit protected to withstand temporary overload condition.
