Dual Channel Central Office ADSL2+ Line
Driver
The EL1537 is a very low power dual channel differentiated
amplifier designed for central office line driving for DMT
ADSL solutions. This device features a high drive capability
of 400mA while consuming only 7.5mA of supply current per
amplifier from ±12V supplies. This driver achieves a typical
distortion of less than -75dBc, at 1MHz into a 50 load. The
EL1537 is available in the thermally-enhanced 28-pin
HTSSOP package. This device is specified for operation
over the full -40°C to +85°C temperature range.
The EL1537 has two control pins, C0 and C1, per channel.
With the selection of C0 and C1, the device can be set into
full-IS power, 3/4-IS power, 1/2-IS power, and power-down
disable modes. The EL1537 maintains excellent distortion
and load driving capabilities even in the lowest power
settings. The EL1537 has extended bandwidth and improved
THD and slew rate for ADSL2+ and VDSL applications.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100% matte
tin plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
