General Description

The MAX4361/MAX4362/MAX4363 are a family of high-

performance ADSL drivers and drivers/receivers ideal

for the upstream transmit path and the downstream

receive path of customer premise equipment. These

devices operate from a single 5V supply and deliver up

to 12.5dBm average line power for DMT modulated sig-

nals, meeting the requirements of full-rate ADSL.

Spurious-free dynamic range (SFDR) at full output

power is typically -75dBC at 100kHz.

The MAX4361 is a differential IN/differential OUT driver

with a fixed gain of 3.1V/V. The MAX4362 is a dual

amplifier with shutdown intended for use as a differen-

tial IN/differential OUT driver with gain set with external

resistors. The MAX4363 is a quad amplifier with shut-

down intended for use as a differential IN/differential

OUT driver/receiver combination with gain set with

external resistors.

The MAX4361 is offered in a space-saving 8-pin µMAX

package.
