MAX4361ESA

Overview

The MAX4361ESA is a high-performance ADSL differential line driver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 5V supply and delivers up to +12.5dBm average line power for DMT modulated signals, meeting full-rate ADSL requirements. The device features a fixed gain of 3.1V/V and achieves a spurious-free dynamic range (SFDR) of typically -75dBc at 100kHz. It includes thermal and short-circuit protection with a peak output current of 280mA minimum. The component is housed in an 8-pin SO package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail output swing capability
• Integrated thermal and short-circuit protection
• Low-noise performance with 4.8nV/√Hz voltage noise density

Applications

• ADSL Line Interface
• HDSL Line Driver

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Ensure compatibility with single 5V supply requirements and check for any recent product change notices or lifecycle status updates before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a fixed-gain differential driver for upstream transmit paths in customer premise equipment. Evaluate thermal dissipation constraints carefully, as high output currents may necessitate adequate heat sinking within the specified ambient temperature limits.

Part Context

This part belongs to the MAX4361/MAX4362/MAX4363 family of ADSL drivers and receivers designed for customer premise equipment. While the MAX4361 is a dedicated driver, the MAX4362 and MAX4363 offer configurable amplifier options with shutdown capabilities for more complex transceiver designs.

Replacement Considerations

Direct replacements include other members of the MAX436x family such as the MAX4362ESD or MAX4363ESP, provided the application can accommodate external gain-setting resistors and separate supply pins.
