MAX4361EUA

Overview

The MAX4361EUA is a high-performance ADSL line driver manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-pin µMAX package. It operates from a single 5V supply and delivers up to +12.5dBm average line power for DMT signals. The device features a fixed gain of 3.1V/V with differential input and output. Key electrical parameters include a typical spurious-free dynamic range (SFDR) of -75dBc at 100kHz, a peak output current of 280mA minimum, and a voltage noise density of 4.8nV/√Hz. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Differential IN/differential OUT architecture optimized for full-rate ADSL upstream transmit paths
• Rail-to-Rail output swing capability ensuring maximum signal utilization on the line
• Integrated thermal and short-circuit protection mechanisms for robust operation
• Low-noise performance suitable for sensitive customer premise equipment applications

Applications

• ADSL Line Interface
• HDSL Line Driver
• Upstream Transmit Path for Customer Premise Equipment

Procurement Notes

Verify the specific ordering suffix 'EUA' corresponds to the 8-pin µMAX package and the -40°C to +85°C industrial temperature range. Confirm that the component meets RoHS compliance requirements as specified in the manufacturer's documentation before finalizing procurement specifications.

Selection Notes

Select this component when a fixed-gain differential driver is required for ADSL applications without the need for external resistor configuration. Ensure the design accommodates the 8-pin µMAX footprint and provides adequate decoupling near the V+ pins to maintain the specified SFDR and power delivery capabilities under load.

Part Context

This part belongs to the MAX4361/MAX4362/MAX4363 family of ADSL drivers and receivers. While the MAX4362 offers dual amplifiers with shutdown and the MAX4363 provides quad amplifiers with integrated receiver channels, the MAX4361 is specifically designed as a standalone driver with fixed internal gain settings.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation.

FAQ

What is the fixed gain of the MAX4361?

The MAX4361 has a fixed gain of 3.1V/V, set by three internal resistors.

How does the MAX4361 handle capacitive loads?

The device is capable of driving capacitive loads up to 2nF. For larger loads, isolation resistors should be used between the output and the load to reduce ringing.

What is the typical Spurious-Free Dynamic Range (SFDR)?

The SFDR at full output power is typically -75dBc at 100kHz.
