EL1527
FN7341.1
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 50Ω 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-I_S power, 3/4-I_S power, 1/2-I_S power, and power-down
disable modes. The EL1527 maintains excellent distortion
and load driving capabilities even in the lowest power
settings.
The EL1527 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.

NOTE: Intersil Pb-free 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-020C.
