AD8541AKSZ-REEL7

Overview

The AD8541AKSZ-REEL7 is a single-channel CMOS rail-to-rail general-purpose operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and consumes a typical supply current of 45 µA per amplifier. The device features 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 25°C. It provides unity gain stability and ensures no phase reversal across the full common-mode input range. The component 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 enables full signal swing in single-supply systems.
• Extremely low input bias current of 4 pA supports high-impedance source applications.
• Low power consumption of 45 µA per amplifier extends battery life in portable designs.
• Guaranteed unity gain stability with no phase reversal across the entire input voltage range.

Applications

• ASIC input or output buffering
• Sensor interfaces
• Piezoelectric transducer amplifiers
• Medical instrumentation
• Portable systems

Procurement Notes

Verify that the specific ordering suffix AKSZ corresponds to the 5-Lead SC70 package configuration before procurement. Confirm RoHS compliance status indicated by the Z suffix. Ensure the reel quantity matches production requirements. Validate automotive qualification if required, noting that standard commercial models differ from AEC-Q100 qualified variants.

Selection Notes

Select this component when low power consumption and rail-to-rail performance are critical. The 4 pA input bias current makes it suitable for high-impedance sources like piezoelectric sensors. Verify that the 1 MHz bandwidth meets system speed requirements. Consider the 5-Lead SC70 package dimensions for space-constrained PCB layouts.

Part Context

This part belongs to the AD854x family of CMOS rail-to-rail amplifiers, which includes dual (AD8542) and quad (AD8544) channel variants. The AD8541 specifically denotes the single-channel version. The AKSZ suffix identifies the 5-Lead SC70 surface-mount package option, distinguishing it from SOT-23 or SOIC package alternatives within the same electrical specification set.

Replacement Considerations

Direct functional substitutes within the same family include AD8541ARTZ-REEL7 (SOT-23 package) and AD8541ARZ (SOIC package). Automotive-grade equivalents are designated with the W suffix, such as AD8541WAKSZ-REEL7, which meet AEC-Q100 standards but may have different reliability specifications.
