AD8016ARBZ

Overview

The AD8016ARBZ is a dual high-output current xDSL line driver in a 24-lead SOIC_W_BAT package. It operates on ±3 V to ±13 V supplies with a typical quiescent current of 12.5 mA per amplifier at full power. The device delivers up to 600 mA linear output current and achieves a slew rate of 1000 V/µs. Bandwidth is 78 MHz at G = +5, with a large-signal bandwidth of 90 MHz. Input offset voltage is typically 1 mV, and the operating temperature range spans from −40°C to +85°C.

Feature Summary

• Integrated digital power management with four programmable bias levels via PWDN logic inputs
• High output current capability of 600 mA for driving low-resistance loads
• On-chip thermal shutdown protection with alarm signal generation via the BIAS pin
• Low single-tone distortion performance suitable for ADSL central office applications

Applications

• ADSL central office (CO) terminal drivers
• HDSL2 line interface circuits
• VDSL system transceivers
• Proprietary xDSL line drivers

Procurement Notes

Verify the specific suffix ARBZ corresponds to the 24-lead SOIC_W_BAT package configuration. Confirm that the ordering part number matches the required thermal pad and lead frame specifications for the target PCB layout. Ensure compatibility with the manufacturer's RoHS3 compliance standards before finalizing procurement documentation.

Selection Notes

Select this component when designing systems requiring high peak output currents into low impedance lines. Evaluate the trade-off between quiescent power consumption and multitone power ratio (MTPR) using the programmable power-down states. Ensure adequate PCB copper area is allocated for thermal dissipation given the internal power limits.

Part Context

This device belongs to Analog Devices' high-performance line driver family designed specifically for digital subscriber line infrastructure. It addresses the need for efficient power usage in central office equipment while maintaining strict signal integrity requirements for broadband data transmission over copper pairs.

Replacement Considerations

Publicly confirmed substitutes include the AD8016ARE, which utilizes a 28-lead TSSOP_EP package with an exposed paddle. Designers must account for the pinout differences and distinct thermal characteristics associated with the alternative package style.
