-52V Dual Channel Differential DSL Line
Driver
The ISL1540 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 ISL1540 is supplied in a thermally-enhanced 8mm x
8mm 32 Ld QFN package and is specified for operating over
the full -40°C to +85°C temperature range.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
