... Generally, in differential amplifiers an external V pin is used to control the common mode level REF of the differential output; in the case of the EL4543 the V of each of the three internal amplifier channels receives a signal from the Logic Encoding Block with encoded H and V information. The final output consists of three ...

... Power Dissipation Calculation When switching at high speeds, or driving heavy loads, the EL4543 drive capability is ultimately limited by the rise in die temperature brought about by internal power dissipation. For reliable operation die temperature must be kept below T (125°C necessary to calculate the power dissipation for a given application prior to selecting package type ...
