Features
Complete two-input fader with output amplifier uses no extra components 80 MHz bandwidth Fast fade control speed Operates on g 5V to g 15V supplies l 60 dB attenuation 5 MHz
General Description
The EL4453C is a complete fader subsystem It variably blends two inputs together for such applications as video picture-inT picture effects he EL4453C operates on g 5V to g 15V supplies and has an analog differential input range of g 2V AC characteristics do T not change appreciably over the supply range he circuit has an operational temperature of b 40 C to a 85 C T and is packaged in 14-pin P-DIP and SO-14 he EL4453C is fabricated with Elantec's proprietary complementary bipolar process which gives excellent signal symmetry C d is free from latch up an
