EL4453

Video Fader

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.

The circuit has an operational temperature of -40°C to +85°C

and is packaged in 14-pin PDIP and SO-14.

The EL4453 is fabricated with Elantec’s proprietary

complementary bipolar process which gives excellent signal

symmetry and is free from latch up.
