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 dissipation 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
be used to adjust supply current to one of four pre-set modes
(full-I
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 QFN packages. The EL1508
is specified for operation over the full -40°C to +85°C
temperature range.

Ordering Information
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.
