AD8531AKSZ-REEL7

Overview

The AD8531AKSZ-REEL7 is a single-channel, rail-to-rail input/output operational amplifier from Analog Devices. It operates on a single supply voltage ranging from 2.7 V to 6 V and delivers 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 consumes 750 μA per amplifier and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Single-supply operation compatible with 2.7 V to 6 V power rails
• High output drive capability of ±250 mA for resistive or capacitive loads
• Rail-to-rail input and output swing maximizing dynamic range
• Low supply current consumption of 750 μA per amplifier

Applications

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

Procurement Notes

Verify the specific package suffix 'KS' corresponds to the 5-lead SC-70 configuration required for your PCB layout. Confirm that the REEL7 designation matches your automated assembly equipment specifications. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range to maintain guaranteed electrical performance parameters.

Selection Notes

Select this component when high load current driving is necessary alongside low power consumption in single-supply systems. It is suitable for applications requiring rail-to-rail signal integrity without phase reversal issues. Consider thermal dissipation limits if driving heavy capacitive loads near maximum current ratings. Verify that the 3 MHz bandwidth meets the AC performance requirements of the target circuit.

Part Context

This part belongs to the AD853x family of low-cost, high-output current amplifiers manufactured by Analog Devices. The AD8531 represents the single-channel variant, while dual and quad versions are available as the AD8532 and AD8534 respectively. All variants share identical electrical characteristics but differ in channel count and package options.

Replacement Considerations

Direct pin-compatible replacements within the same family include the AD8532 (dual) and AD8534 (quad). Other packages such as SOT-23 or SOIC may be used if the footprint allows, provided the electrical specifications remain consistent.
