Datasheet
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.
