Data Sheet
Dual Channel Differential DSL Line Driver
The ISL1532 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.
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).
The ISL1532 operates on ±5V to ±15V supplies and retains
its bandwidth and linearity over the complete supply range.
The device is supplied in a thermally-enhanced
20 Ld HTSSOP and the small footprint (4x5mm) 24 Ld QFN
packages. The ISL1532 is specified for operation over the
full -40°C to +85°C temperature range.
The ISL1532 provides larger output swing at heavy loads,
higherwww.DataSheet4U.com slew rate, and higher bandwidth while maintaining
pin-to-pin drop-in compatibility with the EL1528. The
ISL1532 integrates 50k pull-up resistors on C0 and C1 pins.
