DATASHEET
EL1508
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 IADJ pin. Two other pins (C0 and C1) can
also be used to adjust supply current to one of four pre-set
modes (full-IS, 2/3-IS, 1/3-IS, and full power-down). The
EL1508 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 Ld SOIC
(0.300”), a thermally-enhanced 16 Ld SOIC (0.150”), and the
small footprint (4x5mm) 24 Ld QFN packages. The EL1508
is specified for operation 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.
