The EL4453 is a complete fader subsystem. It variably blends two inputs together for such applications as video picture-in-picture effects.

The EL4453 operates on ±5V to ±15V supplies and has an analog differential input range of ±2V. AC characteristics do not change appreciably over the supply range.
