EL1508 differential dsl line driver the EL1508 is designed for driving full rate adsl signals in both co and cpe applications at very low power dissipation. the high drive capability of 450ma makes this driver ideal for both cap and dmt designs. it contains two wideband, high-voltage, current mode feedback amplifiers with a number of power diss ipation reduction features. these drivers achieve an mtpr distortion measurement of better than 70db, while consuming typically 6ma of total supply current. this supply current can be set using a resistor on the i adj pin. two other pins (c 0 & c 1 ) can also be used to adjust supply current to one of four pre-set modes (full-i s , 2/3-i s , 1/3-i s , and full power-down). the EL1508 operates on 5v to 12v supplies and retains its bandwidth and linearity over the complete supply range. 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. the EL1508 is specified for operation over the full -40c to +85c temperature range. features 450ma output drive capability 43.6v p-p differential output drive into 100 ? 2 nd /3 rd harmonics of -85dbc/-75dbc mtpr of -70db operates down to 3ma per amplifier supply current power control features pin-compatible with el1503 applications adsl line driver hdsl line driver video distribution amplifier video twisted-pair line driver ordering information part number package tape & reel pkg. no.
