Triple 80MHz Video Amplifier with DC

Restore

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 150Ω at video signal

levels. The EL4390 operates on supplies as low as ±4V up to

±15V.

Being a current-mode feedback design, the bandwidth stays

relatively constant at approximately 80MHz over the ±1 to

±10 gain range. The EL4390 has been optimized for use with

1300Ω feedback resistors.

Pinout

The EL4390 is three wideband

current-mode feedback amplifiers

optimized for video performance, each

(16-PIN PDIP, SO)
