AD8534AN

Overview

The AD8534AN is a quad CMOS operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, allowing operation from a single supply voltage ranging from 2.7V to 6V. The device provides a gain-bandwidth product of 3MHz and a slew rate of 5V/us. Key electrical parameters include an input offset voltage of 25mV, input bias current of 60pA, and a quiescent current of 700uA per channel. It supports an output drive current of 250mA and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Quad rail-to-rail input/output architecture for maximum dynamic range in single-supply systems
• High output drive capability suitable for resistive or capacitive loads
• Low power consumption with guaranteed operation at 3V and 5V supplies

Applications

• Single-supply balanced line drivers for multimedia applications
• High output current reference and regulator circuits
• Automotive signal conditioning

Procurement Notes

Verify the package type carefully, as the 'AN' suffix typically denotes a DIP package, whereas official documentation often lists 'AR' (SOIC) or 'ARU' (TSSOP). Confirm availability status directly with the manufacturer or authorized distributors, as stock levels vary. Ensure the specific pinout matches the intended PCB footprint before ordering.

Selection Notes

Select this component when high output current drive is required alongside rail-to-rail performance in low-voltage single-supply designs. It is suitable for applications needing moderate bandwidth and precision without the complexity of dual-supply configurations. Consider thermal management if driving heavy loads continuously.

Part Context

This part belongs to the AD8534 family of precision amplifiers. It shares core specifications with variants like the AD8534ARZ and AD8534ARUZ, differing primarily in the physical package style. The family is designed for general-purpose analog signal processing where low power and wide input/output swing are critical.

Replacement Considerations

Direct substitutes include other quad rail-to-rail op-amps with similar 250mA drive and 3MHz bandwidth. Verify pin compatibility and electrical tolerances against alternatives such as the AD8604 or LMH6629, ensuring the replacement meets the 250mA output requirement.
