High Power Differential Line Driver Features General Description • High power ADSL driver • 39.2VP-P differential output drive into 22Ω • 42.4VP-P differential output drive into 65Ω • Driver 2nd/3rd harmonics of -66dBc/-72dBc at 2VP-P into 100Ω differential • Supply current of 12.5mA per amplifier • Supply current control • Power saving modes • Standard surface-mount packages • Ultra-small LPP package 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 22Ω 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. d n e ns m ig C m s A o e 3 c D 0 e 5 R w 1 ot Ne EL N or e f Us Applications • ADSL line drivers • HDSL2 line drivers • Video distribution amplifiers Ordering Information 13” MDP0046 20-Pin SO (0.300") - MDP0027 EL1503CM-T13 20-Pin SO (0.300") 13” MDP0027 EL1503CS 16-Pin SO (0.150”) - MDP0027 EL1503CS-T7 16-Pin SO (0.150”) 7” MDP0027 EL1503CS-T13 16-Pin SO (0.150”) 13” MDP0027 EL1503CM 20 VOUTB MDP0046 24-Pin LPP EL1503CL-T13 21 VIN-B MDP0046 7” 22 NC - 24-Pin LPP EL1503CL-T7 23 VIN-A 24-Pin LPP EL1503CL 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. 24 VOUTA Outline # Package 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.
