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.
