| EL1503C - Product Brief EL1503C - Product Brief High Power Differential Line Driver Features * High power ADSL driver * 39.2VP-P differential output drive into 22 * 42.4VP-P differential output drive into 65 * Driver 2nd/3rd harmonics of -66dBc/-72dBc at 2VP-P into 100 differential * Supply current of 12.5mA per amplifier * Supply current control * Power saving modes * Standard surface-mount packages * Ultra-small LPP package General Description The EL1503C 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 P-P signal into a 22 load while 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 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. Applications * ADSL line drivers * HDSL2 line drivers * Video distribution amplifiers Ordering Information Part No. EL1503CL EL1503CL-T7 Package Tape & Reel 24-Pin LPP 24-Pin LPP 24-Pin LPP EL1503CL-T13 EL1503CM EL1503CM-T13 EL1503CS EL1503CS-T7 EL1503CS-T13 nd s en m ig C om es 3A ec D 50 R ew 1 ot N EL N or e f Us Pin Configurations 24 VOUTA 7" MDP0046 MDP0046 13" 20-Pin SO (0.300") 20-Pin SO (0.300") MDP0027 d e The EL1503C 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 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 packages are used as ground connections and heat spreaders. The LPP package has the potential for a low JA (<40C/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 -40C to +85C temperature range.
