General Description

The EL4390C is three wideband current-mode feedback amplifiers 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 g4V up to g15V.
