EL1503C - Product Brief
High Power Differential Line Driver
Features
General Description
• High power ADSL driver
• 39.2VP-P differential output drive
into 22W
• 42.4VP-P differential output drive
The EL1503C ADSL Line Driver contains two wideband high-voltage
drivers which are ideally suited for both ADSL and HDSL2 applica-
tions. They can supply a 39.2VP-P signal into a 22W load while
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.
into 65W
• Driver 2nd/3rd harmonics of
-66dBc/-72dBc at 2VP-P into 100W
differential
• Supply current of 12.5mA per
amplifier
• Supply current control
• Power saving modes
• Standard surface-mount packages
• Ultra-small LPP package
The EL1503C uses current-feedback type amplifiers, which achieve a
high slew rate while consuming moderate power. They retain their fre-
quency 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"),
16-pin thermal SO (0.150”), and the small footprint (4x5mm) 24-pin
LPP packages. Center pins on each side of the 20-pin and 16-pin pack-
ages are used as ground connections and heat spreaders. The LPP
package has the potential for a low qJA (<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 tem-
perature range.
Applications
• ADSL line drivers
• HDSL2 line drivers
• Video distribution amplifiers
