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.
Features
· Complete two-input fader with output amplifier--uses no extra components · 80MHz bandwidth · Fast fade control speed · Operates on ±5V to ±15V supplies · > 60dB attenuation @ 5MHz
Applications
· Mixing two inputs · Picture-in-picture · Text overlay onto video · General gain control

CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
