DATASHEET
Dual Channel Differential DSL Line Driver
ISL1532
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 I
ADJ
pin. Two other pins (C
0
and C
1
) can
also be used to adjust supply current to one of four preset
modes (full-I
S
, 3/4-I
S
, 1/2-I
S
and full power-down). C
0
and C
1
inputs are design to pull high initially. Floating these inputs will
put the device in disable mode. This is contrary to EL1528
where C
0
and C
1
inputs pull low initially and is in the enable
state when C0 and C1 pins are floated.
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 across the full -40°C to
+85°C temperature range.
The ISL1532 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 ISL1532
integrates 50k pull-up resistors on C0 and C1 pins.
