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.
