AD8396ACPZ-RL

Overview

The AD8396ACPZ-RL is a dual-port ADSL/ADSL2+ line driver featuring two differential current feedback amplifiers. It operates on dual supplies from ±6 V to ±12 V or single supplies from 12 V to 24 V. The device delivers a typical differential output voltage swing of 43.4 V p-p with a slew rate of 170 V/μs. Quiescent current is 10.8 mA in full power mode and 1.4 mA in shutdown. It provides -66 dBc MTPR at 20.4 dBm output power.

Feature Summary

• Dual-channel architecture with integrated feedback resistors and biasing networks
• High output current capability for driving telephone lines with transformer coupling
• Digitally programmable logic pins for independent port shutdown control
• Low power consumption with distinct active and shutdown states

Applications

• ADSL Central Office (CO) line drivers
• ADSL2+ Central Office (CO) line drivers
• Digital Subscriber Line (xDSL) systems requiring high output voltage swing

Procurement Notes

Verify component status as the datasheet indicates this model is obsolete. Confirm availability through authorized distributors or secondary markets. Ensure the specific ordering suffix matches the required reel quantity and RoHS compliance. Check for valid replacement components if new designs are being developed.

Selection Notes

Select this component for applications requiring high differential output voltage and current drive in DSL environments. Consider the thermal resistance of the 16-lead LFCSP package for heat dissipation. Evaluate supply voltage requirements against the specified 12 V to 24 V range. Verify compatibility with 3.3 V or 5 V CMOS logic for power-down control signals.

Part Context

Analog Devices manufactures the AD8396, a specialized analog interface circuit designed for digital subscriber line infrastructure. This part belongs to the family of high-performance line drivers intended for central office equipment. It addresses the need for robust signal transmission over twisted pair copper wiring in broadband access networks.

Replacement Considerations

The datasheet explicitly marks the AD8396 as obsolete. No direct public substitutes are listed within the provided documentation. Designers should consult Analog Devices for current generation alternatives or evaluate other dual-channel DSL line drivers that meet similar electrical specifications and pinout requirements.
