AD8515ARTZ-R2

Overview

The AD8515ARTZ-R2 is a single-channel, rail-to-rail input and output operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 1.8 V to 5 V. Key electrical specifications include a maximum offset voltage of 6 mV, a typical input bias current of 2 pA, and a gain bandwidth product of 5 MHz. The device features a slew rate of 2.7 V/µs and consumes a maximum supply current of 450 µA at 1.8 V. It is housed in a 5-lead SOT-23 package and is specified for operation over an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output swing capability allows full signal utilization across the supply voltage range.
• Low power consumption with minimal supply current makes it suitable for battery-operated applications.
• Space-saving 5-lead SOT-23 package design facilitates placement near sensors to reduce noise pickup.

Applications

• Portable communications equipment
• Sensor interfaces
• Battery-powered devices

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as the R2 designation indicates cut tape availability. Confirm the RJ-5 package option aligns with PCB footprint requirements. Ensure the component meets RoHS compliance standards if mandated by project specifications. Cross-reference the specific part number against the manufacturer's latest ordering guide to confirm current production status and lead time constraints.

Selection Notes

Select this component when low voltage operation down to 1.8 V is required alongside rail-to-rail performance. Consider the 5 MHz bandwidth and 2.7 V/µs slew rate for driving ASIC inputs such as voice codecs. Evaluate the low input bias current for high-impedance sensor applications. Verify thermal resistance values for the SOT-23 package under expected load conditions to ensure stable operation within the specified temperature range.

Part Context

This component belongs to the AD8515 family of micropower CMOS operational amplifiers. It shares core specifications with variants like the AD8515AKSZ series but differs in package type. The ARTZ suffix denotes an automotive or extended temperature grade compliant with RoHS standards. It serves as a general-purpose amplifier optimized for portable electronics where power efficiency and small form factor are critical design constraints.

Replacement Considerations

Direct substitutes within the same package include AD8515ARTZ-REEL1 and AD8515ARTZ-REEL7. For SC70 package requirements, consider the AD8515AKSZ series variants. Verify pin compatibility and electrical parameter equivalence before substitution.
