EL1503A ® Data Sheet PR ODUC T BRIEF June 7, 2002 High Power Differential Line Driver Features 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 39.2VP-P signal into a 22Ω load while exhibiting very low distortion. The EL1503A also has a number of power saving features. The IADJ pin can be used to set the maximum supply current and the C0 and C1 pins can be used to digitally vary the supply current to one of four modes. These modes include full power, low power, terminate only and power down. • High power ADSL driver 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-pin SO (0.300”), a thermally-enhanced 16-pin SO (0.150”), and the small footprint (4x5mm) 24-pin LPP packages. Center pins on each side of the 20-pin and 16-pin packages are used as ground connections and heat spreaders. The LPP package has the potential for a low θJA (<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.
