AD8396ACPZ-R2

Overview

The AD8396ACPZ-R2 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 differential output voltage swing of 43.4 V p-p into a 100 Ω load with a quiescent current of 10.8 mA in full power mode. It achieves a differential slew rate of 170 V/μs and maintains a typical Multitone Power Ratio (MTPR) of −66 dBc across the 26 kHz to 2.2 MHz band.

Procurement Notes

Verify component status as the datasheet indicates this part is obsolete. Confirm availability through authorized distributors or secondary market suppliers. Ensure the ordering suffix matches the required tape and reel quantity. Check for RoHS compliance markings on the package. Validate that the LFCSP_WQ package option CP-16-26 is compatible with your PCB footprint and assembly processes.

Selection Notes

Select this component for applications requiring high output voltage swing and low distortion in DSL systems. Consider the fixed internal gain of 13 V/V when designing the analog front end interface. Evaluate thermal management strategies given the maximum power dissipation limits. Ensure supply voltages remain within the specified 12 V to 24 V range for proper operation.

Part Context

This device belongs to Analog Devices' portfolio of high-speed operational amplifiers tailored for telecommunications infrastructure. It is specifically engineered to drive telephone lines while compensating for hybrid insertion losses. The LFCSP_WQ package provides a compact solution for space-constrained board layouts in central office equipment.

Replacement Considerations

No direct public substitutes are confirmed in the provided documentation. Due to the obsolete status, alternative solutions may require redesigning the interface circuitry to accommodate different pinouts or gain configurations.
