Description
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.
Applications
- Mixing two inputs
- Picture-in-picture
- Text overlay onto video
- General gain control
