AD8603AUJZ-R2

Overview

The AD8603AUJZ-R2 is a single-channel precision CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply from 1.8 V to 5 V or dual supplies of ±0.9 V to ±2.5 V. Key electrical parameters include a maximum offset voltage of 50 µV, a maximum input bias current of 1 pA, and a typical supply current of 40 µA per amplifier. The device offers a gain-bandwidth product of 316 kHz at 10 kΩ load, a slew rate of 0.1 V/µs, and an input voltage noise density of 25 nV/√Hz at 1 kHz. It is housed in a 5-lead TSOT package.

Feature Summary

• Patented trimming technique achieves superior precision without laser trimming
• Rail-to-rail input and output operation enables full signal swing in low power systems
• No phase reversal occurs even when input voltage exceeds the common-mode range
• Capable of driving large capacitive loads without oscillation

Applications

• Battery-powered instrumentation
• Multipole filters
• Proximity sensors
• Photodiode I-V conversion circuits
• Low power ASIC input or output amplifiers

Procurement Notes

Verify the specific ordering suffix R2 indicates reel packaging with a quantity of 250 units as listed in the official Analog Devices ordering guide. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the component matches the -40°C to +125°C temperature range specification before integration into designs requiring extended industrial operating conditions.

Selection Notes

Select this component for applications requiring micropower consumption alongside high precision. The combination of low offset voltage and low input bias current makes it suitable for sensitive sensor interfaces. Verify that the required bandwidth and slew rate meet the system's dynamic performance needs within the specified 1.8 V to 5 V supply range constraints.

Part Context

This part belongs to the AD8603/AD8607/AD8609 family of precision micropower amplifiers. While the AD8607 and AD8609 offer dual and quad channel configurations respectively, the AD8603AUJZ-R2 provides a single-channel solution in a compact 5-lead TSOT package. This form factor allows for smaller board space utilization compared to larger packages used by other members of the series.

Replacement Considerations

Direct substitutes within the same family include the AD8607 and AD8609 for multi-channel requirements. For single-channel replacements, verify pin compatibility and electrical specifications against the original datasheet requirements.
