FN7014.2
Differential DSL Line Driver
Features
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 dissipation reduction features.
• 450mA output drive capability
• 43.6V differential output drive into 100Ω

• 2 /3 harmonics of -85dBc/-75dBc
• MTPR of -70dB
• Operates down to 3mA per amplifier supply current
• Power control 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
• Pin-compatible with EL1503
• Pb-free available
resistor on the I
pin. Two other pins (C & C ) can also

be used to adjust supply current to one of four pre-set modes
(full-I , 2/3-I , 1/3-I , and full power-down). The EL1508

operates on ±5V to ±12V supplies and retains its bandwidth
and linearity over the complete supply range.
• ADSL line driver
• HDSL line driver
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 QFN packages. The EL1508
is specified for operation over the full -40°C to +85°C
temperature range.
• Video distribution amplifier
• Video twisted-pair line driver

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding
compounds/die attach materials and 100% matte tin plate termination finish, which is
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-020B.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
