AD45048ARZ-REEL

Overview

The AD45048ARZ-REEL is a dual voltage feedback operational amplifier designed for rail-to-rail upstream ADSL line driving. It features a wide supply range from 3.3 V to 24 V and delivers high output current with a linear peak of 230 mA into 25 Ω. The device provides a 65 MHz bandwidth and a 55 V/μs slew rate, ensuring low distortion in high-speed applications. Key electrical parameters include a 4.5 nV/√Hz voltage noise density at 100 kHz, an input offset voltage of 2.5 mV, and a multitone power ratio of −68 dBc.

Feature Summary

• Rail-to-rail output stage capable of swinging within 0.5 V of supply rails
• High output current capability of 230 mA peak into 25 Ω loads
• Fabricated on XFCB-HV process for high speed and low distortion
• Designed specifically for driving upstream signals in ADSL CPE applications

Applications

• Consumer xDSL modems
• Twisted pair line drivers
• ADSL Customer Premises Equipment (CPE) applications
• Audio applications

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the REEL suffix indicates tape-and-reel packaging compatible with automated assembly equipment. Ensure the ARZ designation matches the required lead-free specification and temperature range for the target application environment.

Selection Notes

Select this dual op amp when driving high-fidelity xDSL signals requires high output current and wide dynamic range. It serves as a drop-in replacement for TS613ID and EL1519CS devices. Consider its 65 MHz bandwidth and low noise characteristics for applications demanding minimal distortion in single-supply environments.

Part Context

This part belongs to the Analog Devices AD45048 family of precision amplifiers. It is manufactured using the proprietary XFCB-HV silicon-on-insulator process, which prevents latch-up and enables high-frequency performance. The device is housed in an 8-lead SOIC package suitable for surface-mount installation.

Replacement Considerations

The datasheet explicitly identifies the AD45048 as a drop-in replacement for the TS613ID and EL1519CS components. Engineers replacing these legacy parts should verify pin compatibility and ensure the new device meets the specific current drive requirements of the existing circuit design.
