AD8603AUJZ-REEL

Overview

The AD8603AUJZ-REEL is a single-channel, precision CMOS operational amplifier from Analog Devices. It features rail-to-rail input and output capabilities with a maximum offset voltage of 50 µV and a typical value of 12 µV. The device 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 gain-bandwidth product of 316 kHz at 10 kΩ load, a slew rate of 0.1 V/µs, and a supply current of 40 µA to 50 µA per amplifier. Input bias current is typically 0.2 pA, with a maximum of 1 pA. Voltage noise density is 22 nV/√Hz at 10 kHz. The component is housed in a 5-lead TSOT package and supports an operating temperature range of -40°C to +125°C.

Feature Summary

• Patented trimming technique achieves superior precision without laser adjustment.
• Rail-to-rail input and output swing capability for wide dynamic range.
• No phase reversal 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 amplification

Procurement Notes

Verify the specific reel quantity against the ordering guide suffixes: AUJZ-R indicates a 250-unit reel, while AUJZ-REEL denotes a 10,000-unit reel. Confirm RoHS compliance status marked by the Z suffix. Ensure the 5-lead TSOT package matches the design footprint requirements. Check that the -40°C to +125°C temperature rating aligns with the application environment.

Selection Notes

Select this component for applications requiring low power consumption alongside high precision in a compact form factor. The single-channel configuration suits space-constrained designs where only one amplifier is needed. Consider the rail-to-rail performance if interfacing with low-voltage ADCs or DACs. Evaluate the 316 kHz bandwidth against signal frequency requirements to ensure adequate gain-bandwidth product.

Part Context

This part belongs to the AD8603/AD8607/AD8609 family of micro-power, low-noise CMOS operational amplifiers. While the AD8607 offers dual channels and the AD8609 provides four channels, the AD8603 specifically delivers a single channel. All variants share identical core electrical characteristics, including offset voltage, noise, and power consumption specifications.

Replacement Considerations

Direct functional equivalents within the same series include the AD8607 (dual channel) and AD8609 (quad channel), provided additional channels are acceptable. Verify pin compatibility if substituting between different package types such as MSOP or SOIC, as pinouts may differ despite shared functionality.
