AD8019ARU-REEL

Overview

The AD8019ARU-REEL is a high-speed, low-power current feedback operational amplifier manufactured by Analog Devices. It features a dual-channel configuration housed in a TSSOP-14 surface-mount package. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, with a typical quiescent current of 3.5 mA per channel. It provides a bandwidth of 600 MHz at unity gain and a slew rate of 2500 V/µs, supporting output currents up to 75 mA.

Feature Summary

• Current feedback architecture for high-speed signal processing
• Low power consumption suitable for battery-operated systems
• Rail-to-rail output capability for maximum dynamic range
• Single-supply operation compatible with standard logic levels

Applications

• Video buffering and distribution circuits
• High-speed data acquisition systems
• Portable instrumentation requiring low power
• Communication equipment signal conditioning

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific reel packaging designation matches system requirements. Check for end-of-life status or obsolescence notices prior to final design approval. Ensure compliance with relevant environmental regulations applicable to the target market.

Selection Notes

Select this component when high bandwidth and low power are critical constraints. Compare against voltage feedback alternatives if input impedance characteristics differ significantly. Evaluate thermal performance within the TSSOP-14 package for the intended application environment. Consider pin compatibility with existing board layouts if replacing legacy parts.

Part Context

This part belongs to the AD8019 family of high-speed amplifiers designed for demanding analog signal paths. It complements other devices in the series offering varying speed and power trade-offs. The REEL suffix indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

Consult official substitution guides for electrically equivalent alternatives. Verify pinout compatibility before integrating any cross-reference components. Assess performance margins to ensure functional equivalence in high-frequency applications.
