Data Sheet

Dual Channel Differential DSL Line Driver
The EL1528 is a dual channel differential amplifier designed
for driving full rate ADSL signals at very low power
dissipation. The high drive capability of 450mA makes this
driver ideal for both CAP and DMT designs. It contains two
pairs of wideband, high-voltage, current mode feedback
amplifiers optimized for low power consumption in DSL
systems.
These drivers achieve an MTPR distortion measurement of
better than 70dB, while consuming typically 5mA per DSL
channel of total supply current. This supply current can be
set using a resistor on the I
ADJ
pin. Two other pins (C
0
& C
1
)
can also be used to adjust supply current to one of four pre-
set modes (full-I
S
, 3/4-I
S
, 1/2-I
S
, and full power-down). The
EL1528 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
HTSSOP and the small footprint (4x5mm) 24-pin QFN
packages. The EL1528 is specified for operation over the full
-40C to +85C temperature range.

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-020C.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
