AD8534ARU-REEL

Overview

The AD8534ARU-REEL is a quad-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 750 μA per amplifier at 5 V. Key electrical parameters include a gain bandwidth product of 3 MHz, a slew rate of 5 V/μs, and an input bias current of 5 pA. It is specified over an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• High output current capability of ±250 mA for driving resistive or capacitive loads
• Rail-to-rail input and output operation enabling full signal swing in single-supply systems
• Low supply current consumption of 750 μA per amplifier channel
• Unity gain stable design without phase reversal

Applications

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

Procurement Notes

Verify the specific REEL suffix against the manufacturer's ordering guide to confirm tape-and-reel packaging specifications. Ensure the component matches the required 14-lead TSSOP package dimensions and thermal characteristics. Confirm that the operating environment remains within the specified -40°C to +85°C temperature range to maintain guaranteed performance levels.

Selection Notes

Select this component when high current drive is required alongside low power consumption in single-supply designs. The rail-to-rail I/O feature makes it suitable for buffering CMOS DACs or ASICs where maximum dynamic range is necessary. Consider the thermal resistance of the TSSOP package if driving heavy loads near the maximum junction temperature limit.

Part Context

This part belongs to the AD853x family of low-cost, high-output current amplifiers. The AD8534 specifically provides four independent channels in a 14-lead surface-mount package. It shares core specifications with the single-channel AD8531 and dual-channel AD8532 variants, offering consistent performance across the series for multi-channel applications.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the AD8531 (single channel) and AD8532 (dual channel). Verify that any alternative quad-channel op-amp meets the ±250 mA output current requirement and rail-to-rail input/output specifications.
