AD8541AKSZ-R2

Overview

The AD8541AKSZ-R2 is a single-channel CMOS operational amplifier from Analog Devices, packaged in a 5-lead SC70 format. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical quiescent current of 45 µA per amplifier. The device features rail-to-rail input and output capabilities, ensuring full signal swing across the supply range. Key electrical specifications include a gain-bandwidth product of approximately 1 MHz, an input bias current as low as 4 pA, and a maximum input offset voltage of 6 mV at room temperature. It is specified for operation within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output capability for maximizing dynamic range in single-supply systems
• Ultra-low supply current consumption optimized for battery-powered applications
• Very low input bias current suitable for high-impedance sensor interfaces
• Automotive qualification (AEC-Q100) for reliable performance in demanding environments

Applications

• ASIC input or output buffering
• Piezoelectric transducer amplification
• Photodiode detection circuits
• Portable medical instrumentation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel quantity. Ensure the component meets AEC-Q100 automotive standards if required by the design specification. Cross-reference the datasheet revision to confirm electrical characteristics match the intended application requirements before finalizing procurement.

Selection Notes

Select this component when designing low-power single-supply systems requiring rail-to-rail signal handling. The low 45 µA supply current makes it ideal for extending battery life in portable devices. Consider the 1 MHz bandwidth and low input bias current for applications involving high-impedance sources or moderate-speed signal processing tasks.

Part Context

This part belongs to the AD854x family of general-purpose CMOS amplifiers, which includes dual (AD8542) and quad (AD8544) variants. The family is characterized by improved performance over previous generations, offering higher output current and better AC performance at lower supply voltages while maintaining low power consumption.

Replacement Considerations

Direct substitutes within the same package and pinout include other AD8541 variants such as AD8541ARTZ or AD8541ARZ, provided the package difference is acceptable. For automotive-grade replacements, verify availability of equivalent AEC-Q100 qualified parts.
