AD8603AUJZ-REEL7

Overview

The AD8603AUJZ-REEL7 is a single-channel precision operational amplifier from Analog Devices, housed in a 5-lead TSOT package. It operates on a single supply of 1.8 V to 5 V or dual supplies of ±0.9 V to ±2.5 V. Key electrical specifications 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 features rail-to-rail input and output capabilities, a gain bandwidth product of 316 kHz at RL = 10 kΩ, and a slew rate of 0.1 V/µs. It maintains operation across an extended temperature range of -40°C to +125°C.

Feature Summary

• Utilizes patented trimming technology for superior precision without laser trimming
• Provides rail-to-rail input and output swing for wide dynamic range
• Ensures stability with unity gain configuration and no phase reversal
• Delivers low noise performance suitable for sensitive signal processing

Applications

• Battery-powered instrumentation
• Multipole filters
• Capacitive and inductive sensors
• Low power ASIC input or output amplifiers

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the required packing quantity of 3000 units as listed in the official Analog Devices ordering guide. Confirm that the UJ-5 package marking code A0X matches the physical component received. Ensure compliance with RoHS standards indicated by the Z suffix in the part number before finalizing procurement orders.

Selection Notes

Select this component when designing portable systems requiring high precision with minimal power consumption. The 5-lead TSOT package is ideal for space-constrained layouts. Consider the 40 µA supply current for battery life optimization. Verify that the 316 kHz gain bandwidth product meets the frequency requirements of the target application circuit.

Part Context

This part belongs to the AD8603/AD8607/AD8609 family of micropower, low noise CMOS operational amplifiers. While the AD8607 offers dual channels and the AD8609 provides quad channels, the AD8603 specifically delivers a single-channel solution. All variants share identical core electrical characteristics and are designed for similar low-power, high-precision applications.

Replacement Considerations

Direct functional substitutes within the same family include the AD8607ARMZ (dual channel) and AD8609ARUZ (quad channel), provided additional channels are acceptable. Other packages such as SOIC or MSOP may be used if pin compatibility and board space allow.
