Dual Channel Medium Power Differential Line Driver
The EL1527 is a very low power dual channel differentiated
amplifier designed for central office and customer premise
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 EL1527 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 EL1527 maintains excellent distortion
and load driving capabilities even in the lowest power
settings.
Features
• Drives 360mA at 16VP-P on ±12V supplies
• 40VP-P differential output drive into 100
• -75dBc typical driver output distortion driving 50 at 1MHz
and 1/2-IS bias current
• Low quiescent current of 3.5mA per amplifier in 1/2-IS
mode
• Power-down disable mode
• Pb-free available (RoHS compliant)
Applications
The EL1527 is available in the thermally-enhanced 28 Ld
HTSSOP package. This device is specified for operation
over the full -40°C to +85°C temperature range.

NOTE: These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials, and 100%
matte tin plate plus anneal (e3 termination finish, which is 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.
