General Description
The EL1503AC ADSL Line Driver contains two wideband high-volt-
age drivers which are ideally suited for both ADSL and HDSL2
applications. They can supply a 39.2V
P-P
signal into a 22Ω load while
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
0
and C
1
pins can be used to digitally vary the
supply current to one of four modes. These modes include full power,
low power, terminate only and power down.
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-
ers. The LPP package has the potential for a low
θ
JA
(<40°C/W) and
dissipates heat by means of a thermal pad that is soldered onto the
PCB. All package options are specified for operation over the full
----
-40°C to +85°C temperature range.
Applications
• ADSL line drivers
• HDSL2 line drivers
• Video distribution amplifiers
