Description
The EL4393 is three wideband currentfeedback amplifiers optimized for video performance. Each amplifier can drive a load of 150Ω at video levels. Each amplifier has a disable capability, which is controlled by a TTL/CMOS compatible logic signal. The EL4393 operates on supplies as low as ±4V up to ±15V.
Being a current-feedback design, the bandwidth stays relatively constant at approximately 80MHz over the ±1 to ±10 gain range. The EL4393 has been optimized for use with 1300Ω feedback resistors at a gain of 2. When the outputs are disabled, the supply current consumption drops, by about 4mA per channel that is disabled. This feature can be used to reduce power dissipation.
