Description
The EL1501 contains two wideband high-voltage drivers and two receive amplifiers. It is designed to drive 45VP-P signals at 2MHz into a 200Ω load differentially with very low distortion. The receive amplifiers also provide very low distortion and noise, and with external resistors can be wired as a hybrid coupler.
All amplifiers are of the current-feedback type, giving high slewrates while consuming moderate power. They retain frequency response over a wide range of externally set gains.
The EL1501 operates on ±5V to ±15V supplies, and retains its bandwidths and linearities over the supply range.
Eight center package pins are used as ground connections and heat spreaders, allowing a dissipation of 2W at the maximum ambient temperature of 85oC.
Applications
- ADSL line interface
- HDSL line driver
- Video distribution amplifier
- Video twisted-pair line driver
