The EL4393 is three wideband currentfeedbackamplifiers opTImized for videoperformance. Each amplifier can drivea load of 150Ω at video levels. Each amplifier has a disablecapability, which is controlled by a TTL/CMOS compaTIblelogic signal. The EL4393 operates on supplies as low as ±4Vup to ±15V.Being a current-feedback design, the bandwidth stays relaTIvelyconstant at approximately 80MHz over the ±1 to ±10gain range. The EL4393 has been opTImized for use with1300Ω feedback resistors at a gain of 2.When the outputs are disabled, the supply current consumptiondrops, by about 4mA per channel that is disabled. Thisfeature can be used to reduce power dissipation.
