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

be used to adjust supply current to one of four pre-set modes

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.

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.
