Dual Channel Fixed Gain Differential DSL
Line Driver
The ISL1532A 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 resisitors 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).
The device is supplied in a thermally-enhanced 20 Ld
HTSSOP and the small footprint (4x5mm) 24 Ld QFN
packages. The ISL1532A is specified for operation over the
full -40°C to +85°C temperature range.
The ISL1532A provides larger output swing at heavy loads,

higher slew rate, and higher bandwidth while maintaining
pin-to-pin drop-in compatibility with the EL1528. The
ISL1532A integrates 50k pull-up resistors on CO and C1
pins.
