® FOR UPDATEDELDIN1a5Ft0Oa3RASMh Aee Tt ION SEE July 17, 2001 FN7038.0 High Power Differential Line Driver The EL1503 ADSL Line Driver contains two wideband highvoltage 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 EL1503 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. The EL1503 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 EL1503 operates on ±5V to ±12V supplies and consumes only 12.5m A 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 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.
