AD8604WARZ-RL

Overview

The AD8604WARZ-RL is a quad precision operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical quiescent current of 750 uA per channel. Key electrical parameters include a gain-bandwidth product of 8.2 MHz, a slew rate of 5.2 V/us, and an input offset voltage of 80 uV. The device supports an output current of 50 mA per channel and offers a common-mode rejection ratio of 68 dB. It is housed in a 14-pin SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Quad-channel CMOS architecture with rail-to-rail input and output performance
• Precision specifications including low input offset voltage and bias current
• Automotive qualification compliant with AEC-Q100 standards
• Wide operating temperature range suitable for industrial environments

Applications

• Battery-powered instrumentation systems
• Photodiode amplification circuits
• Active filter implementations
• Data acquisition signal conditioning

Procurement Notes

Verify component authenticity through authorized channels due to restricted availability status. Confirm package integrity and pin alignment against the 14-pin SOIC specification. Ensure storage conditions maintain moisture sensitivity levels prior to soldering. Cross-reference datasheet revisions to validate parameter consistency for critical design integration.

Selection Notes

Select this component when quad-channel precision is required alongside rail-to-rail swing capabilities. Compare gain-bandwidth and offset voltage requirements against alternative models like the AD8604DRZ-REEL for package compatibility. Evaluate power consumption constraints relative to the 750 uA per channel specification. Consider automotive qualification needs when choosing between standard and W-grade variants.

Part Context

This part belongs to the AD8604 series of precision amplifiers, designed for high-performance analog signal processing. It shares architectural similarities with the dual-channel AD8602 and single-channel AD8601 variants. The 'W' suffix indicates an automotive-grade version, while 'ARZ' denotes the specific package type. The '-RL' suffix specifies reel packaging for automated assembly processes.

Replacement Considerations

The AD8604DRZ-REEL serves as a direct functional substitute with identical electrical characteristics but utilizes a different SOIC-14 package variant. Verify pinout compatibility and thermal performance differences between the W and non-W suffixes before substitution.
