General Description

The EL1503C ADSL Line Driver contains two wideband high-voltage

drivers which are ideally suited for both ADSL and HDSL2 applica-

exhibiting very low distortion. The EL1503C also has a number of

power saving features. The IADJ pin can be used to set the maximum

supply current to one of four modes. These modes include full power,

low power, terminate only and power down.

The EL1503C uses current-feedback type amplifiers, which achieve a

high slew rate while consuming moderate power. They retain their fre-

quency response over a wide range of externally set gains. The

EL1503C operates on ±5V to ±12V supplies and consumes only

12.5mA per amplifier.

The device is supplied in a standard form-factor 20-pin SO (0.300"),

16-pin thermal SO (0.150”), and the small footprint (4x5mm) 24-pin

LPP packages. Center pins on each side of the 20-pin and 16-pin pack-

ages are used as ground connections and heat spreaders. The LPP

package has the potential for a low

by means of a thermal pad that is soldered onto the PCB. All package

options are specified for operation over the full -40°C to +85°C tem-

perature range.
