High Power Differential Line Driver

The EL1503A ADSL Line Driver contains two wideband high-voltage drivers which are ideally suited for both ADSL and HDSL2 applications. They can supply a 39.2V into a 22Ω load while exhibiting very low distortion. The EL1503A also has a number of power saving features. The I

pin can be used to set the maximum supply current and

ADJ

the C

and C1 pins can be used to digitally vary the supply

0

current to one of four modes. These modes include full power, low power, terminate only and power down.

The EL1503A uses current-feedback type amplifiers, which achieve a high slew rate while consuming moderate power. They retain their frequency response over a wide range of externally set gains. The EL1503A operates on ±5V to ±12V supplies and consumes only 12.5mA per amplifier.

The device is supplied in a thermally-enhanced 20 Ld SOIC (0.300”) and the small footprint (4x5mm) 24 Ld QFN packages. Center pins on each side of the 20 Ld and 16 Ld packages are used as ground connections and heat spreaders. The QFN package has the potential for a low (<40°C/W) and dissipates heat 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 temperature range.
