The EL2141 is a very high bandwidth amplifier whose outputis in differenTIal form, and is thus primarily targeted for applicaTIonssuch as driving twisted pair lines, or any applicaTIonwhere common mode injecTIon is likely to occur. The inputsignal can be in either single-ended or differential form, butthe output is always in differential form.On the EL2141, two feedback inputs provide the user withthe ability to set the device gain, (stable at minimum gain oftwo).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 voltagereference.The transmission of ADSL/HDSL signals requires very lowdistortion amplification, so this amplifier was designed withthis as a primary goal. The actual signal distortion levelsdepend upon input and output signal amplitude, as well asthe output load impedance. (See distortion data inside.)Both outputs (VOUT, VOUTB) are short circuit protected towithstand temporary overload condition.
