EL2141CSZ

150MHz的差分双绞线驱动器 150MHz Differential Twisted Pair Driver

The EL2141 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. Gen erally, this pin is grounded, but it can be tied to any voltage reference.
