-52V Dual Channel Differential DSL Line Driver
The ISL1541 is a -52V dual channel differential amplifier designed for driving full rate ADSL signals at very low power dissipation. The high supply voltage allows operation from a single standard -52V negative battery supply. It contains two pairs of wideband, high voltage, current mode feedback amplifiers optimized for lower power consumption and highest performance in ADSL and ADSL2+ systems. The line drivers have fixed gain AV = 48 with integrated feedback and gain resistors. Its output clamping circuit eliminates the requirement for the Zener protection diodes. These drivers achieve an MTPR distortion measurement of better than 70dB while consuming typically 3mA per DSL channel of total supply current. The ISL1541 is supplied in a thermally-enhanced 6mm x 6mm 24 Ld QFN package and is specified for operating over the full -40°C to +85°C temperature range.
