AD8541ARTZ-REEL7

Overview

The AD8541ARTZ-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 with a typical supply current of 45 µA per amplifier. The device features a gain bandwidth product of approximately 1 MHz and an input bias current as low as 4 pA. It provides unity gain stability, no phase reversal, and supports output currents up to 30 mA at 5 V. The component is housed in a 5-lead SOT-23 package and is specified for operation across the extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output capability enables full signal swing utilization in single-supply systems.
• Extremely low supply current consumption of 45 µA optimizes battery life in portable applications.
• High input impedance with minimal bias current facilitates interfacing with high-impedance sensors.
• Unity gain stable design ensures reliable performance without external compensation components.

Applications

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

Procurement Notes

Verify that the specific part number matches the required 5-lead SOT-23 packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering suffix corresponds to the correct reel quantity and tape specifications for automated assembly processes.

Selection Notes

Select this component when low power consumption is critical alongside moderate bandwidth requirements. The rail-to-rail architecture suits single-supply designs where maximizing dynamic range is necessary. Consider the 4 pA input bias current for high-impedance source applications requiring minimal loading effects.

Part Context

This model belongs to the AD854x family of CMOS amplifiers, which includes dual (AD8542) and quad (AD8544) variants. The series is designed to provide improved performance over previous generations, specifically offering lower supply current while maintaining a 1 MHz gain bandwidth. The ARTZ suffix indicates the commercial grade version in a 5-lead SOT-23 package.

Replacement Considerations

Direct pin-compatible substitutes within the same family include the AD8541AKSZ-REEL7, which utilizes a 5-lead SC70 package instead of SOT-23. Other channel counts such as the AD8542 or AD8544 may be considered if multiple channels are required, provided the package constraints allow.
