AD8615AUJZ-R2

Overview

The AD8615AUJZ-R2 is a single-channel, precision CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7 V to 5.0 V. The device exhibits a maximum offset voltage of 100 µV at 25°C and up to 800 µV across the extended industrial temperature range of -40°C to +125°C. Key electrical parameters include a gain bandwidth product of 23 MHz, a slew rate of 12 V/µs, and a typical supply current of 2 mA per amplifier. Input bias current is specified at 1 pA typical.

Feature Summary

• Patented DigiTrim trimming technique achieves superior precision without laser trimming
• Immune to output phase reversal when input common-mode voltage exceeds rails
• Capable of driving high capacitive loads with external compensation networks

Applications

• Multipole active filters
• High-speed photodiode preamplifiers
• Buffering DAC outputs in data acquisition systems
• Portable battery-powered instrumentation

Procurement Notes

Verify the specific suffix 'R2' against the manufacturer's ordering guide to confirm tape and reel packaging specifications. Ensure the component matches the exact pinout for the 5-lead TSOT-23 package. Cross-reference the revision level (Rev. G) with the latest datasheet to confirm parameter updates. Confirm RoHS compliance status as indicated in the documentation.

Selection Notes

Select this component for applications requiring high DC accuracy combined with wide signal bandwidth. The low input bias current makes it suitable for high-impedance sensor interfaces. Consider thermal resistance limits when designing for heavy load currents or high ambient temperatures. Verify that the single-supply operation aligns with system power constraints.

Part Context

This part belongs to the AD8615/AD8616/AD8618 family of precision amplifiers. While the AD8616 offers dual channels and the AD8618 provides four channels, the AD8615 is configured as a single amplifier. All variants share identical core performance characteristics, including noise density and bandwidth, but differ in channel count and physical package configurations.

Replacement Considerations

Direct functional substitutes within the same family include the AD8616 and AD8618, provided multi-channel requirements are met. Other packages such as MSOP or SOIC may be compatible if pinouts match, though the TSOT-23 form factor is unique to the AD8615.

FAQ

Does the AD8615 experience output phase reversal?

No, the AD8615 is immune to phase inversion even when the input voltage exceeds the supply rails.

How does the DigiTrim technology benefit the AD8615?

It allows the device to achieve superior precision and low offset voltage without using laser trimming during manufacturing.
