AD8532ARUZ

Overview

The AD8532ARUZ is a dual-channel, single-supply operational amplifier manufactured by UMT (UMW). It features rail-to-rail input and output capabilities with a high output drive current of ±250 mA. The device operates within a supply voltage range of 2.7 V to 6 V and draws a typical supply current of 750 μA per amplifier at 5 V. Key electrical specifications include a gain bandwidth product of 3 MHz, a slew rate of 5 V/μs, and an offset voltage of 25 mV. It is unity-gain stable and designed for low-noise applications.

Feature Summary

• Provides high output drive capability suitable for resistive or capacitive loads
• Features rail-to-rail input and output swing for maximum dynamic range
• Ensures stability without phase reversal under various load conditions
• Maintains low power consumption while delivering significant output current

Applications

• Multimedia audio signal processing
• LCD driver circuits
• ASIC input or output buffering
• Headphone drivers

Procurement Notes

Verify the manufacturer marking on the component body matches UMW specifications. Confirm the package type corresponds to TSSOP-8 as indicated by the RU suffix. Ensure the part number aligns with the dual-channel configuration rather than single or quad variants within the AD853x family. Check datasheet revisions for any updates to electrical characteristics.

Selection Notes

Select this component when a dual-channel amplifier requires both high current drive and low power consumption in a single-supply system. It is appropriate for designs needing rail-to-rail performance to maximize signal swing near supply rails. Consider the 3 MHz bandwidth and 5 V/μs slew rate for audio and moderate-speed signal conditioning tasks.

Part Context

This device belongs to the AD8531/AD8532/AD8534 family of low-cost, single-supply amplifiers. The AD8532 specifically provides two independent channels in one package, whereas the AD8531 offers a single channel and the AD8534 provides four. All share similar electrical characteristics but differ in channel count and pin configurations.

Replacement Considerations

Check for equivalent dual-channel rail-to-rail amplifiers from other manufacturers if UMW stock is unavailable. Verify that substitute parts match the ±250 mA output current, 3 MHz bandwidth, and TSSOP-8 package dimensions to ensure mechanical and electrical compatibility.
