Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD829SQ/883B with the AD9631ANZ is based on the following criteria:

Common Substitution Parameters:

• Manufacturer: Both devices are manufactured by Analog Devices Inc.
• Category: Both are classified as Linear Amplifiers
• Mounting Type: Both utilize through-hole mounting technology
• Package Footprint: Both employ 8-pin DIP packages with 0.300" (7.62mm) spacing, ensuring mechanical compatibility on printed circuit boards
• Product Status: Both devices maintain Active product status
• Compliance: Both are RoHS3 compliant and REACH unaffected
• Moisture Sensitivity: Both are rated MSL 1 (Unlimited)

Functional Differences: The AD9631ANZ operates as a single-circuit voltage feedback amplifier, whereas the AD829SQ/883B functions as a dual-circuit general-purpose amplifier. The AD9631ANZ exhibits significantly higher slew rate (1300V/µs versus 230V/µs) and bandwidth performance (-3dB bandwidth of 320 MHz), but operates with higher supply current (17 mA versus 5.3 mA) and requires a narrower supply voltage span (6V to 12V versus ±4.5V to ±18V).

Parameter Comparison

Engineering Selection Recommendations

AD829SQ/883B Selection Criteria: The AD829SQ/883B is the appropriate choice for applications requiring dual-channel amplification with lower power consumption (5.3 mA supply current) and extended supply voltage range (±4.5V to ±18V). This device is suitable for general-purpose amplification tasks where moderate slew rate performance (230V/µs) is acceptable and dual-circuit integration reduces component count.

AD9631ANZ Selection Criteria: The AD9631ANZ is appropriate for single-channel applications demanding higher performance specifications, including elevated slew rate (1300V/µs), higher bandwidth (-3dB bandwidth of 320 MHz), and increased output current capability (70 mA per channel). This device is suitable when application requirements exceed the performance envelope of the AD829SQ/883B and single-channel operation is acceptable. The AD9631ANZ operates within a constrained supply voltage range (6V to 12V) and exhibits higher supply current consumption (17 mA).

Both devices maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment and long-term availability. Selection between these devices depends on circuit architecture requirements (single versus dual channel), power budget constraints, and performance specifications rather than compliance or availability factors.

Frequently Asked Questions (FAQ)

Q: Can the AD9631ANZ directly replace the AD829SQ/883B in existing circuit designs?

A: Direct replacement is not recommended without circuit redesign. While both devices share identical 8-pin DIP package footprints and through-hole mounting compatibility, the AD9631ANZ is a single-circuit device versus the dual-circuit architecture of the AD829SQ/883B. Additionally, the AD9631ANZ requires a narrower supply voltage range (6V to 12V) compared to the AD829SQ/883B (±4.5V to ±18V). Circuit topology modifications are necessary to accommodate these functional and electrical differences.

Q: What are the package compatibility considerations between these devices?

A: Both the AD829SQ/883B and AD9631ANZ utilize 8-pin DIP packages with 0.300" (7.62mm) spacing, providing identical through-hole footprints on printed circuit boards. The mechanical pin spacing and board layout compatibility are equivalent. However, internal pin functionality differs between the devices, requiring schematic and layout verification before substitution.

Q: Are there supply voltage compatibility issues when considering substitution?

A: Yes. The AD829SQ/883B operates across a wide supply voltage range (±4.5V to ±18V), while the AD9631ANZ requires a narrower range (6V to 12V minimum to 12V maximum span). Circuits designed for the extended voltage range of the AD829SQ/883B may not operate correctly with the AD9631ANZ without power supply modifications.

Q: How do the performance specifications compare between these amplifiers?

A: The AD9631ANZ provides superior high-frequency performance with a slew rate of 1300V/µs and -3dB bandwidth of 320 MHz, compared to the AD829SQ/883B slew rate of 230V/µs. The AD9631ANZ also delivers higher output current per channel (70 mA versus 32 mA). However, the AD829SQ/883B offers lower power consumption (5.3 mA versus 17 mA supply current) and dual-circuit integration.

Q: Are both devices suitable for the same application categories?

A: Both devices are classified as general-purpose linear amplifiers from Analog Devices Inc. and maintain Active product status. However, application suitability depends on specific performance requirements. The AD829SQ/883B is appropriate for general-purpose dual-channel applications with moderate performance requirements, while the AD9631ANZ is suited for single-channel applications demanding higher slew rate and bandwidth performance.

Q: What compliance and regulatory considerations apply to both devices?

A: Both the AD829SQ/883B and AD9631ANZ are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.33.0001. Both devices carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints. These regulatory and compliance characteristics are equivalent between the two devices.
