Dual Channel Fixed Gain Differential DSL
Line Driver
The ISL1534 is a dual channel differential amplifier designed
for driving full rate ADSL2+ signals at very low power
dissipation. The high drive capability of 450mA makes this
driver ideal for DMT designs. It contains two pairs of
wideband, high-voltage, current mode feedback amplifiers
designed on Intersil’s HS30 Bipolar SOI process for low
power consumption in DSL systems. The amplifiers have an
internal fixed gain, which helps eliminate both feedback and
gain resistors reducing board size and cost.
These drivers achieve an MTPR distortion measurement of
better than 70dB, while consuming typically 5mA per DSL
channel of total supply current. This supply current can be
set using a resistor on the IADJ pin. Two other pins (C0 and
C1) can also be used to adjust supply current to one of four
pre-set modes (full IS, 3/4 IS, 1/2 IS, and full power-down).
C0 and C1 inputs are design to pull high initially. Floating
these inputs will put the device in disable mode. This is
contrary to EL1528 where C0 and C1 inputs pull low initially
and is in the enable state when C0 and C1 pins are floated.
The device is supplied in a thermally-enhanced small

footprint (4mmx5mm) 24 Ld QFN packages. The ISL1534 is
specified for operation over the full -40°C to +85°C
temperature range.
The ISL1534 provides larger output swing at heavy loads,
higher slew rate, and higher bandwidth while maintaining
pin-to-pin drop-in compatibility with the ISL1532A. The
ISL1534 integrates 50k pull-up resistors on C0 and C1 pins.

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.
1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
