Overview
The MAX4363EUP+ 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. The device features a typical Spurious-Free Dynamic Range (SFDR) of -75dBc at 100kHz. Key electrical parameters include a gain-bandwidth product of 190MHz, open-loop gain of 77dB, and peak output current of 25mA. It provides rail-to-rail output swing and includes thermal and short-circuit protection.
Feature Summary
- Quad amplifier configuration with independent shutdown control
- Low-noise performance suitable for high-fidelity signal processing
- Integrated thermal and short-circuit protection mechanisms
- Rail-to-rail output capability for maximum dynamic range
Applications
- ADSL Line Interface
- HDSL Line Driver
- Customer Premise Equipment Transmitter/Receiver
Procurement Notes
Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Ensure the package type matches the 20-pin TSSOP format indicated by the 'P' suffix in the part number. Confirm that the temperature range meets the operational requirements of the intended environment before finalizing procurement.
Selection Notes
Select this component when a quad amplifier with shutdown functionality is required for ADSL applications. Consider the 20-pin TSSOP package for space-constrained designs. Evaluate the power dissipation characteristics relative to the ambient temperature and heat sinking capabilities of the target PCB layout to ensure reliable operation within the specified junction temperature limits.
Part Context
The MAX4363EUP+ belongs to the MAX4361/MAX4362/MAX4363 family of high-performance ADSL drivers and receivers. While the MAX4361 offers fixed gain and the MAX4362 provides dual amplifiers, the MAX4363 integrates four amplifiers to support combined driver and receiver functions in customer premise equipment.
Replacement Considerations
Direct substitutes within the same family include the MAX4363ESP in a 20-pin SO package. For functional equivalents with different pinouts or packaging, consult the manufacturer's cross-reference documentation to verify compatibility with ADSL line interface requirements.
FAQ
What is the typical voltage noise density of the receiver section?
The receiver section has a typical voltage noise density of 8.5nV/√Hz at 1MHz.
How does the shutdown mode affect power consumption?
When the SHDN pin is pulled high, the supply current drops to approximately 70µA, placing the outputs in a high-impedance state.
What is the maximum capacitive load the device can drive?
The MAX4363 is capable of driving capacitive loads up to 10nF while maintaining stability.
