AD8018ARUZ-REEL

Overview

The AD8018ARUZ-REEL is a dual high-speed current feedback amplifier designed for single-supply xDSL applications. It operates within a supply voltage range of 3.3 V to 8 V, with typical performance specified at 5 V. The device delivers a slew rate of 300 V/µs and maintains a bandwidth of 130 MHz at unity gain. Key electrical characteristics include a maximum input offset voltage of 15 mV, a typical supply current of 9 mA per amplifier in full power mode, and an output current capability of 400 mA into a differential load.

Feature Summary

• Rail-to-rail output voltage swing enabling operation close to power supply rails
• High output current drive capability suitable for low impedance loads
• Integrated digital logic control for selectable full power, standby, and shutdown modes

Applications

• xDSL USB, PCI, and PCMCIA cards
• Consumer DSL modems
• Twisted pair line drivers

Procurement Notes

Verify the specific package configuration matches the required PCB footprint, as the component is available in both SOIC and TSSOP variants. Confirm that the REEL suffix corresponds to the tape and reel packaging format intended for automated assembly processes. Ensure compatibility with the target operating temperature range of -40°C to +85°C for the final application environment.

Selection Notes

Select this component when designing single-supply systems requiring high output current and low distortion for driving transformer-coupled lines. The integrated power-down features allow for efficient power management in portable devices. Consider the thermal dissipation limits of the TSSOP package when operating near maximum supply voltages or delivering high line power levels.

Part Context

This part belongs to the AD8018 family of high-speed amplifiers manufactured by Analog Devices Inc. utilizing the XFCB process technology. The ARU designation indicates the 14-lead TSSOP package variant, while the REEL suffix specifies the bulk tape packaging method. This series is optimized for cost-effective customer premise equipment implementations.

Replacement Considerations

Public confirmed substitutes are not identified in the provided documentation. Verify pinout and functional compatibility before substituting with other high-speed operational amplifiers, particularly regarding the specific digital control logic requirements for power-down modes.
