Triple 80MHz Video Amplifier with DC Restore
DATASHEET
FN7164 Rev 0.00 November 1994
The EL4390 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 150 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 1300 feedback resistors.
