AD8532AR

Overview

The AD8532AR is a dual-channel, single-supply operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with a high output drive current of ±250 mA. The device operates on a supply voltage range of 2.7 V to 6 V, consuming only 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 input offset voltage maximum of 25 mV. It is specified over an extended industrial temperature range from -40°C to +85°C and is housed in an 8-lead SOIC package.

Feature Summary

• High output current capability for driving resistive or capacitive loads
• Rail-to-rail input and output swing for single-supply systems
• Low supply current consumption per channel
• Unity-gain stable with no phase reversal

Applications

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

Procurement Notes

Verify the specific suffix 'R' corresponds to the 8-lead SOIC package configuration as defined in the manufacturer's ordering guide. Confirm that the component meets the required RoHS compliance standards for your manufacturing process. Ensure the operating environment remains within the specified -40°C to +85°C temperature range to maintain guaranteed performance parameters.

Selection Notes

Select this component when high load drive current is required alongside low power consumption in single-supply designs. It is suitable for applications needing rail-to-rail signal integrity without phase reversal issues. Consider thermal dissipation limits if driving heavy loads near the maximum junction temperature rating.

Part Context

This part belongs to the AD853x family, which includes single (AD8531), dual (AD8532), and quad (AD8534) channel variants. All members share identical electrical characteristics and pinouts where applicable, differing primarily in channel count and package options. This family is designed for cost-sensitive, high-performance analog signal processing tasks.

Replacement Considerations

Direct functional substitutes within the same series include AD8531 and AD8534, provided the channel count matches the design requirements. Other packages for the AD8532 model, such as MSOP or TSSOP, offer equivalent electrical performance with different physical footprints.
