EL4390: Triple 80MHz Video Amplifier with DC Restore

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 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.

Key Features
  • 80MHz -3dB bandwidth for gains of 1 to 10
  • 800V/µs slew rate
  • 15MHz bandwidth flat to 0.1dB
  • Excellent differential gain and phase
  • TTL/CMOS compatible DC restore function
  • Available in 16-pin PDIP, 16-pin SOL
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
