ISL1533A
Dual Channel Differential DSL Line Driver
The ISL1533A is a dual channel differential amplifier designed
for driving high crest factor signals at very low distortion levels.
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 with the Renesas
HS30 Bipolar SOI process for low power consumption in
Asymmetric Digital Subscriber Line (ADSL) and Power Line
Communications (PLC) systems. This process provides very
rugged protection against lightning induced surges on the line.
The supply current can be set using a resistor on the IADJ pin.
Pins C0 and C1 can adjust supply current to one of four preset
modes (full-IS, 3/4-IS, 1/2-IS, and full power-down). The
ISL1533A integrates 50k pull-up resistors on Pins C0 and C1 to
initially disable the device.
The ISL1533A operates on ±5V to ±15V supplies or a single
supply up to 30V and retains its bandwidth and linearity across
the complete full scale supply range.
The device is supplied in a thermally-enhanced small footprint
(4mmx5mm) 24 Ld QFN package. The ISL1533A is specified
for operation across the full -40°C to +85°C temperature
range.

NOTES:
1. See TB347 for details about reel specifications.
2. These 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). 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.
3. For Moisture Sensitivity Level (MSL), see the ISL1533A device page. For more information about MSL, see TB363.
