The EL4390 is three widebandcurrent-mode feedback amplifiersoptimized for video performance, eachwith a DC restore amplifier. The DC restore function isactivated by a common TTL/CMOS compatible control signalwhile each channel has a separate restore reference.Each amplifier can drive a load of 150Ω at video signallevels. The EL4390 operates on supplies as low as ±4V up to±15V.Being a current-mode feedback design, the bandwidth staysrelatively constant at approximately 80MHz over the ±1 to±10 gain range. The EL4390 has been optimized for use with1300Ω feedback resistors.
