EL1503AC - Product Brief
High Power Differential Line Driver
Features
General Description
• High power ADSL driver
The EL1503AC ADSL Line Driver contains two wideband high-volt-
age drivers which are ideally suited for both ADSL and HDSL2

exhibiting very low distortion. The EL1503AC also has a number of
power saving features. The IADJ pin can be used to set the maximum
supply current and the C and C pins can be used to digitally vary the

The EL1503AC uses current-feedback type amplifiers, which achieve
a high slew rate while consuming moderate power. They retain their
frequency response over a wide range of externally set gains. The
EL1503AC operates on ±5V to ±12V supplies and consumes only
12.5mA per amplifier.
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 LPP packages. Center pins on each side of the 20-pin
and 16-pin packages are used as ground connections and heat spread-
