AD8531ARTZ-REEL

Overview

The AD8531ARTZ-REEL is a single-channel, rail-to-rail input/output operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 6 V and provides a high output drive current of ±250 mA. The device features a gain bandwidth product of 3 MHz and a slew rate of 5 V/μs at 5 V supplies. Input bias current is typically 50 pA, with an offset voltage of 25 mV. It is unity-gain stable, exhibits no phase reversal, and functions within an extended industrial temperature range of −40°C to +85°C.

Feature Summary

• High output drive capability of ±250 mA suitable for resistive or capacitive loads
• Rail-to-rail input and output operation on single-supply systems
• Low supply current consumption of approximately 750 μA per amplifier
• Unity-gain stability without output phase reversal

Applications

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

Procurement Notes

Verify the specific package suffix 'ARTZ' corresponds to the 8-lead SOIC configuration before integration. Confirm that the REEL designation matches the required tape-and-reel quantity for automated assembly processes. Ensure the component meets RoHS compliance standards applicable to your manufacturing region. Cross-reference the datasheet revision F specifications against your design requirements to validate performance margins.

Selection Notes

Select this component when high load current driving is required alongside low power consumption in single-supply environments. The rail-to-rail characteristics make it suitable for interfacing with CMOS DACs or ASICs where maximum dynamic range is necessary. Consider thermal dissipation limits if operating near the maximum junction temperature, as the device lacks internal short-circuit protection.

Part Context

This part belongs to the AD853x family, which includes dual (AD8532) and quad (AD8534) channel variants. All members share identical electrical characteristics but differ in channel count and package options. The AD8531 specifically offers a single amplifier configuration, providing a compact solution for applications requiring only one high-current buffer or driver stage.

Replacement Considerations

Direct functional substitutes within the same family include the AD8532 and AD8534, provided additional channels are acceptable. Other packages for the AD8531 such as SC70 or SOT-23 may be used if pin compatibility allows.
