AD8534ARUZ-REEL

Overview

The AD8534ARUZ-REEL is a quad rail-to-rail input/output single-supply amplifier featuring 250 mA output drive current. It operates from a 2.7 V to 6 V supply, with guaranteed performance at 3 V and 5 V. Key electrical parameters include a 3 MHz gain bandwidth product, 5 V/μs slew rate, 25 mV maximum offset voltage, and 750 μA supply current per amplifier. The device offers low input bias currents of 50 pA and unity gain stability.

Feature Summary

• Features high output current capability for driving resistive or capacitive loads
• Provides rail-to-rail input and output swing on a single supply
• Ensures no phase reversal within the specified common-mode range
• Maintains unity gain stability without requiring external compensation

Applications

• Multimedia audio amplification
• LCD drivers
• ASIC input or output buffering
• Headphone drivers

Procurement Notes

Verify the specific REEL suffix against the manufacturer's ordering guide to confirm tape-and-reel packaging specifications. Ensure the component matches the exact Analog Devices part number to avoid compatibility issues with existing circuit designs. Cross-reference the datasheet revision date to confirm the accuracy of all listed electrical characteristics before finalizing procurement.

Selection Notes

Select this component when high output current drive is required alongside rail-to-rail signal integrity in single-supply systems. The quad configuration allows multiple channels to be utilized within a compact footprint. Consider the thermal resistance of the TSSOP package if operating near maximum load currents to ensure junction temperatures remain within safe limits during continuous operation.

Part Context

This component belongs to the AD8531/AD8532/AD8534 family of low-cost, high-output current amplifiers manufactured by Analog Devices. The AD8534 specifically provides four independent channels in a single package. The family is designed for applications requiring robust drive capabilities while maintaining low power consumption and wide bandwidth performance across industrial temperature ranges.

Replacement Considerations

Direct substitutes within the same family include the AD8531 (single channel) and AD8532 (dual channel). Verify pinout compatibility and package dimensions when transitioning between different channel counts within the series.
