-52V Dual Channel Differential DSL Line
Driver
Features
• 100mA output current driving capability
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
• Operates from a single -40V to -60V power supply
• 800mW per channel total power dissipation
• MTPR of -70dB
• 96V
P-P
differential output swing
• Fixed gain, integrated gain resistors
• Current control pins
line drivers have fixed gain A = 48 with integrated feedback
V
and gain resistors. Its output clamping circuit eliminates the
requirement for the Zener protection diodes.
• Output clamp for lightning and surge protection
• Channel separation
- 75dB @ 1MHz
These drivers achieve an MTPR distortion measurement of
better than 70dB while consuming typically 3mA per DSL
channel of total supply current.
• Pb-Free plus anneal available (RoHS compliant)
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.
Applications
• Dual port ADSL and ADSL2+ line drivers
• HDSL, HDSL2, HDSL 4 and SHDSL line drivers
• DSLAM, DLC, MDU/MTU line drivers
• Performance upgrade to Le87213, Le87213A, Le87220
• Pin to Pin replacement for Le87220

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.
