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 on Intersil’s HS30
Bipolar SOI process for low power consumption in Asymmetric
Digital Subscriber Line (ADSL) and Power Line Communications
(PLC) systems. This process also provides for 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 also be used to 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
C0 and C1 pins to initially disable the device.
The ISL1533A operates on ±5V to ±15V supplies or single
supply up to 30V and retains its bandwidth and linearity over
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 over the full -40°C to +85°C temperature range.
