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

can also be used to adjust supply current to one of four pre-

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

-40°C to +85°C 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.
