AD8532ARMZ-REEL

Overview

The AD8532ARMZ-REEL is a dual rail-to-rail input/output single-supply operational amplifier manufactured by Analog Devices. It features a high output drive current of ±250 mA, making it suitable for driving resistive or capacitive loads. The device operates on a single supply voltage ranging from 2.7 V to 6 V and is guaranteed to function at 3 V and 5 V supplies. Key electrical specifications include a gain bandwidth product of 3 MHz, a slew rate of 5 V/μs, and a typical supply current of 750 μA per amplifier. It is specified over an extended industrial temperature range of −40°C to +85°C.

Feature Summary

• Dual channel configuration with rail-to-rail input and output capabilities for maximum dynamic range in single-supply systems.
• High output drive current capability of ±250 mA allows direct driving of heavy capacitive loads such as LCD panels without external buffering.
• Low supply current consumption of 750 μA per amplifier enables efficient control of high-current loads while maintaining low power usage.
• Unity gain stable design with no phase reversal ensures reliable operation across the full common-mode input voltage range.

Applications

• Multimedia audio amplification for computers, sound ports, and set-top boxes
• Single-supply balanced line drivers
• Single-supply stereo headphone drivers
• LCD panel drive circuits

Procurement Notes

Verify the specific package suffix RM corresponds to the 8-lead MSOP form factor required for your PCB layout. Confirm that the REEL designation matches your automated assembly equipment requirements. Ensure the component meets the extended industrial temperature rating if operating in environments outside standard commercial ranges. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and revision status before integration.

Selection Notes

Select this component when a dual-channel amplifier requires significant current drive capability directly from a single supply rail. It is appropriate for applications needing rail-to-rail signal swing without the complexity of dual supplies. Consider thermal dissipation limits if driving heavy loads near the maximum junction temperature. Verify that the 3 MHz bandwidth and 5 V/μs slew rate meet the signal fidelity requirements of the target application.

Part Context

This device belongs to the AD853x family of low-cost, high-output current 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 the number of integrated amplifiers. The family is designed for cost-sensitive multimedia and automotive applications requiring robust load driving performance.

Replacement Considerations

Direct functional substitutes within the same family include the AD8531ARZ (single channel) and AD8534ARZ (quad channel). For equivalent performance in different packages, consider the AD8532ARZ (SOIC-8) or AD8532RUZ (TSSOP-8). Verify pin compatibility and thermal characteristics when substituting between package types.
