Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD822ARMZ-R2 is determined by the following critical parameters: dual-circuit configuration, rail-to-rail output architecture, general-purpose amplifier classification, 8-MSOP surface mount packaging, and compatible supply voltage range. The substitute parts identified maintain these core functional and mechanical characteristics while offering either identical specifications or enhanced performance within acceptable operational boundaries.

Direct Equivalent (Packaging Variant): The AD822ARMZ-REEL represents a direct functional equivalent, differing only in packaging format (Cut Tape & Digi-Reel versus standard tape). All electrical specifications remain identical.

Similar Substitute (Performance Enhancement): The TSB572IYST provides functional substitution with enhanced specifications in certain parameters while maintaining dual-circuit, rail-to-rail, general-purpose amplifier architecture in compatible 8-MSOP packaging. This part introduces automotive-grade qualification and extended temperature range capability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): The AD822ARMZ-REEL is the primary substitute for the obsolete AD822ARMZ-R2. Both parts maintain identical electrical specifications and 8-MSOP packaging. The AD822ARMZ-REEL carries Active product status and ROHS3 compliance, providing regulatory continuity for new designs and production restocking.

For Enhanced Performance Applications: The TSB572IYST from STMicroelectronics provides functional substitution with performance enhancements including higher output current capability (65 mA versus 20 mA per channel), extended temperature range (-40°C to 125°C), and automotive-grade AEC-Q100 qualification. This part is suitable for applications requiring higher drive capability or extended thermal operation. The TSB572IYST operates at lower supply current (380 µA per channel versus 1.24 mA) and supports a broader supply voltage range (4V to 36V). Trade-offs include reduced slew rate (1 V/µs versus 3 V/µs) and higher input offset voltage (1.5 mV versus 400 µV).

Both substitute parts are Active products with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory alignment with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the AD822ARMZ-REEL be used as a direct replacement for the AD822ARMZ-R2?

A: Yes. The AD822ARMZ-REEL is electrically and mechanically identical to the AD822ARMZ-R2. The difference is packaging format: the REEL variant is supplied on Cut Tape and Digi-Reel, while the original uses standard tape. Both parts are 8-MSOP surface mount packages with identical pin configurations and electrical specifications.

Q: What are the key differences between the AD822ARMZ-R2 and the TSB572IYST?

A: Both are dual-circuit, rail-to-rail general-purpose amplifiers in 8-MSOP compatible packages. The TSB572IYST offers higher output current (65 mA versus 20 mA per channel), lower supply current consumption, extended temperature range to 125°C, and automotive-grade qualification. The AD822ARMZ-R2 provides higher slew rate (3 V/µs versus 1 V/µs) and lower input offset voltage (400 µV versus 1.5 mV).

Q: Is the TSB572IYST suitable for all applications using the AD822ARMZ-R2?

A: The TSB572IYST is functionally compatible for applications requiring dual-circuit, rail-to-rail amplification within the overlapping supply voltage range (5V to 30V). Applications sensitive to slew rate or input offset voltage specifications require circuit-level evaluation. The TSB572IYST's enhanced output current capability makes it suitable for higher-load applications.

Q: What is the package compatibility between these parts?

A: All three parts use 8-MSOP or 8-MiniSO surface mount packages with 0.118" (3.00mm) width. Pin configurations are compatible for dual-circuit operational amplifier applications. PCB footprints designed for 8-MSOP accommodate all listed substitutes.

Q: Are there compliance or regulatory differences between these parts?

A: The AD822ARMZ-REEL and TSB572IYST are both ROHS3 compliant and REACH unaffected. The TSB572IYST carries AEC-Q100 automotive qualification, making it suitable for automotive and high-reliability applications. All parts have unlimited moisture sensitivity rating (MSL 1).

Q: What inventory considerations apply to these substitutes?

A: The AD822ARMZ-R2 is obsolete with limited stock (793 pcs). The AD822ARMZ-REEL is Active with higher availability (10,024 pcs). The TSB572IYST is Active with 2,530 pcs available. For long-term production, the AD822ARMZ-REEL or TSB572IYST are recommended based on application requirements.
