AD8394ACPZ-RL

Overview

The AD8394ACPZ-RL is a quad operational amplifier featuring four current feedback amplifiers with high output current capability. It supports dual-supply operation from ±6 V to ±12 V and single-supply operation from 12 V to 24 V. The device delivers a slew rate of 300 V/μs and maintains low distortion with an MTPR down to −70 dBc. Internal power dissipation is rated at 700 mW while driving a 20.4 dBm ADSL2+ signal with a CF of 5.5.

Feature Summary

• Four current feedback amplifiers optimized for high output current drive
• Selectable bias modes including three active power states plus shutdown
• Low leakage current in shutdown mode
• High speed performance with 300 V/μs slew rate

Applications

• ADSL/ADSL2+ central office line drivers
• xDSL line drivers
• DAC output buffers
• Medical instrumentation

Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm that the ACPZ suffix corresponds to the 24-lead LFCSP package (4 mm × 5 mm) rather than the AREZ TSSOP_EP variant. Ensure design compatibility with the specified supply voltage ranges and thermal requirements for the quad amplifier configuration.

Selection Notes

Select this component when designing systems requiring high peak current drive and low distortion for digital subscriber line interfaces. The quad architecture allows integration of multiple driver channels within a single footprint. Consider the available power modes for optimizing energy consumption during idle periods or system standby states.

Part Context

The AD8394 is part of Analog Devices' portfolio of broadband operational amplifiers designed for telecommunications infrastructure. This specific quad configuration consolidates four independent amplifiers into one package, facilitating compact board layouts for central office equipment and high-performance analog signal processing applications.
