The EL4453 is a complete fadersubsystem. It variably blends twoinputs together for such applicationsas video picture-in-picture effects.The EL4453 operates on ±5V to ±15V supplies and has ananalog differential input range of ±2V. AC characteristics donot change appreciably over the supply range.The circuit has an operational temperature of -40°C to +85°Cand is packaged in 14-pin PDIP and SO-14.The EL4453 is fabricated with Elantec’s proprietarycomplementary bipolar process which gives excellent signalsymmetry and is free from latch up.
