MAX4363EUP-T

Overview

The MAX4363EUP-T is a quad amplifier with shutdown, designed for ADSL driver/receiver 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 Spurious-Free Dynamic Range (SFDR) of -75dBc at 1MHz, a gain-bandwidth product of 190MHz, and a slew rate of 160V/µs. The device features low voltage noise density (8.5nV/√Hz) and current noise density (0.5pA/√Hz). It provides rail-to-rail output swing and includes thermal and short-circuit protection. The component is housed in a 20-pin TSSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Quad amplifier architecture with independent shutdown control for driver and receiver sections
• Low-noise performance optimized for high-fidelity signal transmission in ADSL systems
• Rail-to-rail output capability ensuring maximum dynamic range on a single 5V supply
• Integrated thermal and short-circuit protection mechanisms

Applications

• ADSL Line Interface for Customer Premise Equipment
• Upstream transmit path drivers
• Downstream receive path amplifiers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the part number matches the exact quad amplifier configuration required for your design. Check for RoHS compliance status if environmental regulations apply to your project.

Selection Notes

Select this component for designs requiring integrated driver and receiver functionality in a single package. The MAX4363 allows for external gain setting via resistors, offering flexibility compared to fixed-gain alternatives. Consider the 20-pin TSSOP footprint during PCB layout. Verify that the 5V supply constraint aligns with your system's power architecture.

Part Context

The MAX4363 belongs to the MAX4361/MAX4362/MAX4363 family of high-performance ADSL drivers and receivers. While the MAX4361 offers a fixed-gain differential driver and the MAX4362 provides a dual amplifier, the MAX4363 integrates four amplifiers to serve as both driver and receiver stages. This integration simplifies the design of full-rate ADSL customer premise equipment by reducing component count.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official distributor databases or contact Analog Devices directly for qualified replacement options compatible with the 20-pin TSSOP package and ADSL application requirements.
