AD8541ARTZ-REEL

Overview

The AD8541ARTZ-REEL 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 characteristics include a maximum offset voltage of 6 mV and an input bias current as low as 4 pA. It is housed in a 5-lead SOT-23 package and supports operation across 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
• Extremely low input bias current suitable for high-impedance source applications
• Unity gain stable design without phase reversal issues
• Optimized AC performance at lower supply voltages

Applications

• ASIC input or output amplifiers
• Sensor interfaces
• Piezoelectric transducer amplifiers
• Photodiode amplifiers
• Portable battery-powered systems

Procurement Notes

Verify the specific suffix 'REEL' indicates a 10,000-unit tape and reel packaging format. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the ordering code matches the exact 5-lead SOT-23 package variant required for your PCB layout. Cross-reference the revision history for any specification updates prior to final procurement.

Selection Notes

Select this component when low power consumption is critical alongside moderate bandwidth requirements. The 4 pA input bias current makes it superior to bipolar alternatives for high-impedance sensors. Verify that the 30 mA output drive capability meets load requirements. Consider the AEC-Q100 qualification if automotive reliability standards are necessary for the application environment.

Part Context

This part belongs to the AD854x family, which includes dual (AD8542) and quad (AD8544) variants. The ARTZ designation specifically identifies the 5-lead SOT-23 surface-mount package. The REEL suffix denotes bulk tape packaging intended for automated assembly processes. It serves as a low-power alternative to higher-current counterparts like the AD8531.

Replacement Considerations

Direct pin-compatible substitutes within the same package include AD8541ARTZ-REEL7 (3,000-unit reel). For different packaging needs, consider AD8541ARZ for 8-lead SOIC configurations. Automotive-grade equivalents are available under the AD8544W series, though specifications may differ.
