AD8230YRZ Equivalent & Substitute Parts

Part Overview

The AD8230YRZ is an active zero-drift operational amplifier manufactured by Analog Devices Inc., designed for precision analog signal conditioning applications. This single-circuit, rail-to-rail amplifier operates across a supply voltage range of 8V to 16V and is housed in an 8-SOIC surface mount package. The device is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when application requirements permit alternative amplifier topologies, supply voltage ranges, or circuit configurations while maintaining package compatibility and surface mount deployment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8230YRZ is evaluated based on the following critical parameters that define functional equivalence and application compatibility:

Package Compatibility: Both the main part and substitute must utilize the 8-SOIC surface mount package to ensure PCB layout and assembly process compatibility.

Output Configuration: Rail-to-rail output capability is maintained across all substitute candidates to preserve signal swing characteristics in the application circuit.

Mounting Technology: Surface mount deployment is required for all substitutes to align with manufacturing and assembly specifications.

Supply Voltage Range: The substitute part must operate within or encompass the required supply voltage window. The AD8230YRZ operates from 8V to 16V; substitutes with wider supply ranges (such as 3V to 36V) are acceptable for applications that do not require the full extended range.

Product Status and Compliance: Only Active status parts with RoHS3 compliance and REACH unaffected designation are considered for substitution to maintain regulatory and environmental standards.

Manufacturer Consistency: Analog Devices Inc. parts are grouped together to ensure design continuity and supply chain reliability.

Engineering Selection Recommendations

AD8230YRZ Selection Criteria:

The AD8230YRZ zero-drift amplifier is the primary selection for applications requiring ultra-low input offset voltage (20 µV) and minimal input bias current (150 pA) within the 8V to 16V supply range. This device maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory compliance and long-term availability. The single-circuit configuration and lower slew rate (2 V/µs) are appropriate for precision DC and low-frequency signal conditioning where offset drift minimization is critical.

AD823ARZ Substitution Criteria:

The AD823ARZ J-FET amplifier serves as a substitute when application requirements permit alternative amplifier topology and expanded supply voltage operation (3V to 36V). This part offers higher slew rate capability (25 V/µs) and lower input bias current (5 pA), making it suitable for applications requiring faster signal response or operation across wider supply ranges. The dual-circuit configuration provides additional flexibility for multi-stage amplification designs. Both parts maintain identical 8-SOIC package specifications, surface mount deployment, Active product status, RoHS3 compliance, and REACH unaffected designation. The AD823ARZ operating temperature range extends to 85°C maximum, which is lower than the AD8230YRZ (125°C maximum).

Frequently Asked Questions (FAQ)

Q: Can the AD823ARZ directly replace the AD8230YRZ in all applications?

A: Direct replacement is possible only when the application does not require the AD8230YRZ's zero-drift topology and ultra-low input offset voltage specification. The AD823ARZ J-FET amplifier exhibits 700 µV input offset voltage compared to 20 µV for the AD8230YRZ. Applications sensitive to offset drift or requiring precision DC amplification must retain the AD8230YRZ. Both parts share identical 8-SOIC package geometry and surface mount characteristics, enabling physical PCB compatibility.

Q: What are the supply voltage compatibility considerations?

A: The AD8230YRZ operates from 8V to 16V, while the AD823ARZ operates from 3V to 36V. The AD823ARZ can substitute in applications using the 8V to 16V range, but the AD8230YRZ cannot substitute in applications requiring operation below 8V or above 16V. Applications operating at the lower voltage boundary (3V to 8V) or upper boundary (16V to 36V) require the AD823ARZ.

Q: Are there circuit topology differences between these parts?

A: Yes. The AD8230YRZ is a zero-drift amplifier with one circuit, while the AD823ARZ is a J-FET amplifier with two circuits. These represent different amplifier architectures with distinct input bias current, offset voltage, and slew rate characteristics. Circuit design modifications may be required when substituting between these topologies.

Q: What is the maximum operating temperature difference?

A: The AD8230YRZ operates to 125°C, while the AD823ARZ operates to 85°C maximum. Applications requiring operation above 85°C must use the AD8230YRZ. The AD823ARZ is suitable for applications with maximum operating temperature requirements of 85°C or lower.

Q: Are both parts available in the same packaging format?

A: Yes. Both the AD8230YRZ and AD823ARZ are supplied in 8-SOIC (0.154", 3.90mm width) surface mount packages with identical physical dimensions. PCB layout and assembly processes remain unchanged between these parts.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are Active product status, RoHS3 compliant, and REACH unaffected. Moisture sensitivity level is 1 (unlimited) for both parts. Regulatory and environmental compliance requirements are satisfied by either part.
