MAX4362ESD+

Overview

The MAX4362ESD+ is a dual amplifier with shutdown, packaged in a 14-pin SOIC. It operates from a single 5V supply (4.5V to 5.5V) and delivers up to +12.5dBm average line power for DMT signals. Key electrical parameters include a typical open-loop gain of 81 dB, a -75dBc spurious-free dynamic range at full output power, and a peak output current of 280mA minimum. The device features rail-to-rail output swing, low voltage noise density of 4.8nV/√Hz, and thermal and short-circuit protection.

Feature Summary

• Dual amplifier architecture with external resistor gain setting
• Low-power shutdown mode for reduced quiescent current
• Rail-to-rail output swing capability
• Integrated thermal and short-circuit protection

Applications

• ADSL Line Interface
• HDSL Line Driver
• Full-rate ADSL ATU-R Line Drivers and Receivers

Procurement Notes

Verify the component against official Maxim Integrated datasheets to confirm pinout compatibility and electrical specifications. Ensure the operating temperature range meets system requirements. Check for RoHS compliance status as indicated in the ordering information. Confirm package dimensions match the PCB footprint design constraints before finalizing procurement decisions.

Selection Notes

Select this part when designing differential input/output drivers requiring adjustable gain via external resistors. Consider the 14-pin SOIC package for board space availability. Evaluate the shutdown feature if power management during idle states is critical. Compare performance metrics like noise density and output swing against alternative ADSL driver solutions.

Part Context

The MAX4362 belongs to the MAX4361/MAX4362/MAX4363 family of high-performance ADSL drivers and receivers. While the MAX4361 offers fixed gain and the MAX4363 provides quad amplification for combined driver/receiver functions, the MAX4362 specifically provides dual uncommitted amplifiers. This configuration allows designers flexibility in setting gain levels using external components.

Replacement Considerations

Direct substitutes within the same family include the MAX4361ESA+ for fixed-gain applications or the MAX4363ESP+ for integrated driver/receiver needs. Verify that any replacement maintains the 14-pin SOIC package or adapts to available pin-compatible alternatives.
