General Description
The EL4390C is three wideband current-mode feedback amplifi-
ers optimized for video performance each with a DC restore
amplifier The DC restore function is activated by a common
TTL CMOS compatible control signal while each channel has a
separate restore reference
Each amplifier can drive a load of 150X at video signal levels
The EL4390C operates on supplies as low as
g
4V up to
g
15V
Being a current-mode feedback design the bandwidth stays rel-
atively constant at approximately 80MHz over the
g
1 to
g
10
gain range The EL4390C has been optimized for use with
1300X feedback resistors
Applications
RGB drivers requiring DC
restoration
RGB multiplexers requiring DC
restoration
RGB building blocks
Video gain blocks requiring DC
restoration
Sync and color burst processing
