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.
The MAX4361, MAX4362, and MAX4363 are a family of high‑performance ADSL drivers and driver/receiver circuits intended for the upstream transmit and downstream receive paths of customer‑premise equipment. They operate from a single 5 V supply and can deliver up to 12.5 dBm average line power, meeting full‑rate ADSL requirements.
The document provides absolute maximum ratings, detailed electrical characteristics for both driver and receiver sections, pin descriptions, recommended power‑supply decoupling, layout guidelines, and typical operating curves. Application notes cover power‑supply design, capacitive‑load driving, and transformer selection for optimal performance.

The devices operate with a supply voltage from –0.3 V to +6 V.
They can deliver up to 12.5 dBm average line power.
Typical spurious‑free dynamic range is –75 dBc at 100 kHz.
When SHDN is pulled high, the supply current drops to about 70 µA.
