AD8534ARU

Overview

The AD8534ARU is a quad rail-to-rail input/output single-supply operational amplifier from Analog Devices. It operates on a 2.7 V to 6 V supply and delivers ±250 mA output current. Key electrical parameters include a 3 MHz gain bandwidth product, 5 V/µs slew rate, and 750 µA supply current per amplifier at 5 V. The device features low input bias current (max 50 pA), 25 mV offset voltage, and unity gain stability. It supports resistive and capacitive loads without phase reversal.

Feature Summary

• Provides high output drive capability of ±250 mA for driving heavy loads
• Features rail-to-rail input and output swing for maximum dynamic range
• Ensures stable operation with capacitive loads up to 10 nF directly
• Operates without output phase reversal within the common-mode input range

Applications

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

Procurement Notes

Verify the specific suffix 'RU' corresponds to the 14-lead TSSOP package configuration as defined in the official ordering guide. Confirm that the component meets the required industrial temperature specifications (-40°C to +85°C) for your application environment. Ensure proper handling procedures are followed due to ESD sensitivity inherent to CMOS input stages.

Selection Notes

Select this component when high output current drive is required alongside low power consumption in single-supply systems. It is suitable for applications needing rail-to-rail signal integrity and stability under capacitive loading conditions. Consider thermal dissipation limits if operating near maximum load currents or elevated ambient temperatures.

Part Context

This part belongs to the AD853x family, which includes single-channel (AD8531) and dual-channel (AD8532) variants. All members share identical electrical characteristics but differ in channel count and package options. The AD8534 specifically integrates four independent amplifiers in a compact surface-mount footprint.

Replacement Considerations

Direct functional substitutes within the same series include the AD8531 and AD8532, provided pin compatibility and channel requirements align with the design constraints.
