General Description
The EL1503C ADSL Line Driver contains two wideband high-voltage
drivers which are ideally suited for both ADSL and HDSL2 applications. They can supply a 39.2V
exhibiting very low distortion. The EL1503C also has a number of
power saving features. The IADJ pin can be used to set the maximum
supply current and the C0 and C1 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 EL1503C 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
EL1503C operates on ±5V to ±12V supplies and consumes only
12.5mA per amplifier.
The device is supplied in a standard form-factor 20-pin SO (0.300"),
o
16-pin thermal SO (0.150”), and the small footprint (4x5mm) 24-pin
c
LPP packages. Center pins on each side of the 20-pin and 16-pin packages are used as ground connections and heat spreaders. The LPP
package has the potential for a low θ
w
by means of a thermal pad that is soldered onto the PCB. All package
e
options are specified for operation over the full -40°C to +85°C temperature range.
