Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC2023ISO8X is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-SOIC surface mount package with identical 0.154" (3.90mm) width to ensure PCB layout compatibility without redesign.

Circuit Configuration: The substitute must provide dual amplifier circuits (2 circuits minimum) to match the original dual-channel functionality.

Output Architecture: Rail-to-rail output capability is required to maintain signal swing characteristics across the specified supply voltage range.

Supply Voltage Range: The substitute must operate within or encompass the 2.5 V to 12 V supply span of the original part.

Output Current: The substitute must deliver a minimum of 60 mA per channel to support equivalent load driving capability.

Thermal Operating Range: The substitute must support the -40°C to 85°C operating temperature window or an extended range that includes this specification.

The ADA4841-2YRZ meets all these substitution criteria while offering enhanced performance characteristics and active product status.

Engineering Selection Recommendations

The ADA4841-2YRZ is the manufacturer-recommended substitute for the obsolete CLC2023ISO8X. Selection of this substitute is supported by the following engineering factors:

Product Status: The ADA4841-2YRZ maintains active product status with ongoing manufacturer support, ensuring long-term availability and supply chain continuity compared to the obsolete CLC2023ISO8X.

Regulatory Compliance: The ADA4841-2YRZ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original part's compliance status is not specified.

Package and Pinout Compatibility: Both devices use identical 8-SOIC surface mount packaging, enabling direct PCB layout compatibility without redesign.

Functional Equivalence: The substitute provides dual rail-to-rail amplifier circuits with matching output current capability (60 mA per channel) and identical supply voltage maximum (12 V). The minimum supply voltage of the substitute (2.7 V) is 0.2 V higher than the original (2.5 V), which is acceptable for most applications operating above 2.7 V.

Performance Enhancement: The ADA4841-2YRZ offers improved specifications including lower input offset voltage (40 µV vs. 880 µV), reduced supply current (1.2 mA vs. 1.85 mA per dual channels), higher bandwidth (80 MHz vs. 25 MHz), and extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C).

Critical Design Consideration: Applications requiring operation at supply voltages below 2.7 V must verify compatibility, as the substitute's minimum supply specification exceeds the original part's minimum by 0.2 V.

Frequently Asked Questions (FAQ)

Q: Can the ADA4841-2YRZ be used as a direct replacement for the CLC2023ISO8X without PCB modifications?

A: Yes, for most applications. Both devices use the 8-SOIC surface mount package with identical physical dimensions and pinout compatibility. No PCB layout changes are required. However, verify that your application's minimum supply voltage is 2.7 V or higher, as the substitute's minimum supply specification is 0.2 V higher than the original.

Q: What is the primary reason for substituting the CLC2023ISO8X?

A: The CLC2023ISO8X is classified as obsolete. The ADA4841-2YRZ is an active product with ongoing manufacturer support, ensuring continued availability and supply chain reliability.

Q: Are there performance differences between the CLC2023ISO8X and ADA4841-2YRZ?

A: Yes. The ADA4841-2YRZ provides enhanced performance: input offset voltage is reduced from 880 µV to 40 µV, bandwidth increases from 25 MHz to 80 MHz, and supply current decreases from 1.85 mA to 1.2 mA per dual channels. These improvements are beneficial for most applications.

Q: Does the substitute meet current environmental regulations?

A: Yes. The ADA4841-2YRZ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the input bias current difference, and does it matter?

A: The ADA4841-2YRZ has a higher input bias current (3 µA vs. 340 nA). For applications with high-impedance input sources or precision transimpedance configurations, this difference may require circuit analysis to confirm compatibility.

Q: Are both devices available in the same packaging options?

A: The CLC2023ISO8X is specified in 8-SOIC packaging. The ADA4841-2YRZ is available in 8-SOIC (Tube packaging). Both use identical physical package dimensions, ensuring mechanical compatibility.

Q: What is the operating temperature range difference?

A: The CLC2023ISO8X operates from -40°C to 85°C, while the ADA4841-2YRZ operates from -40°C to 125°C. The substitute provides an extended upper temperature range, which is advantageous for high-temperature applications.

Q: Can I use the ADA4841-2YRZ in applications requiring the full 2.5 V minimum supply voltage of the original part?

A: No. The ADA4841-2YRZ requires a minimum supply voltage of 2.7 V. Applications operating at 2.5 V to 2.6 V are not compatible with the substitute and require alternative solutions.
