AD8532ARU-REEL

Overview

The AD8532ARU-REEL 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, drawing 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 input offset voltage of 25 mV. It is specified over an extended industrial temperature range from −40°C to +85°C.

Feature Summary

• Dual-channel architecture with rail-to-rail input and output swing capability for maximum dynamic range in single-supply systems.
• High output drive current of ±250 mA enables direct driving of resistive or capacitive loads without external buffering.
• Low power consumption of 750 μA per amplifier allows efficient control of high-current loads while maintaining low system heat dissipation.
• Unity-gain stable design ensures stability when driving heavy capacitive loads such as LCD panels.

Applications

• Multimedia audio amplification for computers, sound ports, and set-top boxes
• Single-supply balanced line drivers for automotive and multimedia applications
• Stereo headphone drivers requiring high current output
• LCD drivers capable of handling heavy capacitive loads

Procurement Notes

Verify the specific ordering suffix RU corresponds to the 8-lead TSSOP package configuration required for your PCB layout. Confirm that the REEL designation matches your automated assembly equipment requirements. Ensure the component meets the extended industrial temperature range specifications if operating in environments outside standard commercial limits.

Selection Notes

Select this component when a dual-channel amplifier is needed with significant current drive capability exceeding standard op-amps. It is suitable for applications requiring rail-to-rail signal integrity near supply rails. Consider thermal management constraints due to the high output current potential, ensuring the package thermal resistance supports the expected load conditions within the junction temperature limits.

Part Context

This part belongs to the AD853x family of low-cost, single-supply amplifiers which includes the single-channel AD8531 and quad-channel AD8534 variants. All members share identical electrical characteristics and pinouts where applicable, differing only in channel count. The family is designed for cost-sensitive applications requiring robust performance in portable and battery-powered devices.

Replacement Considerations

Direct functional replacements within the same family include the AD8531 (single channel) and AD8534 (quad channel). Verify package compatibility when substituting between these variants. No other manufacturer parts are confirmed as direct substitutes based on available documentation.
