EL1503A
High Power Differential Line Driver
The EL1503A 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
P-P
signal into a 22
load while exhibiting very low distortion.
The EL1503A also has a number of power saving features.
The I
ADJ
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 EL1503A 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 EL1503A 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 spreaders. The LPP package
has the potential for a low
JA
(<40C/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 -40C to +85C temperature range.
