AD8541ARTZ-R2

Overview

The AD8541ARTZ-R2 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 with a typical supply current of 45 µA per amplifier. The device features a gain bandwidth product of approximately 1 MHz and a slew rate up to 0.92 V/µs at 5 V. Input bias current is typically 4 pA, supporting high-impedance applications. It is housed in a 5-lead SOT-23 package.

Feature Summary

• Rail-to-rail input and output capability for maximum dynamic range in single-supply systems
• Extremely low input bias current suitable for high-impedance sensor interfaces
• Unity gain stable with no phase reversal across the full common-mode voltage range
• Optimized AC performance at lower supply voltages

Applications

• ASIC input or output buffering
• Sensor interfaces
• Piezoelectric transducer amplifiers
• Photodiode amplifiers

Procurement Notes

Verify the specific suffix 'R2' against the official Analog Devices Ordering Guide. The provided datasheet lists 'REEL' (10,000 units) and 'REEL7' (3,000 units) packaging options for the ARTZ variant. Confirm that the R2 designation corresponds to an authorized tape-and-reel quantity and does not indicate a non-standard or obsolete configuration before procurement.

Selection Notes

Select this component when battery life is critical due to its low 45 µA supply current consumption. It is appropriate for designs requiring rail-to-rail signal swing near the supply rails. Ensure the application benefits from the 1 MHz bandwidth and low noise characteristics while operating within the specified -40°C to +125°C temperature range.

Part Context

This part belongs to the AD854x family, which includes dual (AD8542) and quad (AD8544) variants. The family shares identical electrical specifications but differs in channel count and package options. The ARTZ suffix specifically denotes the 5-lead SOT-23 surface-mount package.

Replacement Considerations

Direct functional replacements include the AD8541AKSZ-REEL7 (SC70 package) or other AD8541 variants listed in the manufacturer's ordering guide. Verify pinout compatibility and thermal resistance differences when substituting packages.
