MAX4362EUB-T

Overview

The MAX4362EUB-T is a dual amplifier with shutdown, designed for ADSL line driver applications. 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 voltage-noise density of 4.8nV/√Hz and current-noise density of 1.5pA/√Hz. The device features rail-to-rail output swing, 280mA minimum peak output current, and -75dBc SFDR at full output power. It includes thermal and short-circuit protection and is housed in a 10-pin µMAX package.

Feature Summary

• Dual amplifier architecture with external gain setting via resistors
• Low-power shutdown mode reducing supply current to 70µA
• Rail-to-rail output swing capability on a single 5V supply
• Integrated thermal and short-circuit protection

Applications

• ADSL ATU-R Line Drivers
• HDSL Line Drivers
• Customer Premise Equipment Upstream Transmit Paths

Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated to ensure authenticity. Check RoHS compliance status against the latest datasheet revision. Validate the operating temperature range of -40°C to +85°C matches application requirements before procurement.

Selection Notes

Select the MAX4362EUB-T when a dual amplifier configuration with external gain control is required for ADSL drivers. Choose this part over the fixed-gain MAX4361 if circuit flexibility is needed. Ensure the design accommodates the 10-pin µMAX package constraints. Verify that the single 5V supply requirement aligns with the system power architecture.

Part Context

The MAX4362 belongs to the MAX4361/MAX4362/MAX4363 family of high-performance ADSL drivers and receivers. While the MAX4361 offers a fixed gain of 3.1V/V and the MAX4363 provides a quad amplifier receiver combination, the MAX4362 specifically provides a dual amplifier solution. This allows designers to configure custom gain settings using external resistors for differential input/output applications.

Replacement Considerations

The MAX4361EUA serves as a functional alternative if a fixed gain of 3.1V/V is acceptable and an 8-pin package is preferred. For applications requiring integrated receiver functionality, the MAX4363 series may be considered despite its quad amplifier structure.
