CLC2008ISO8X Equivalent & Substitute Parts Reference

Part Overview

The CLC2008ISO8X is a general purpose operational amplifier featuring dual circuits in an 8-SOIC surface mount package. Manufactured by MaxLinear, Inc., this device provides rail-to-rail output capability with a 50V/µs slew rate and 33 MHz gain bandwidth product. The part is classified as obsolete, making equivalent substitute components necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility across electrical performance parameters, package form factor, and operating specifications to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLC2008ISO8X is determined by the following mandatory criteria:

Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure PCB layout and assembly process compatibility.

Dual Circuit Configuration: Substitute parts must contain exactly 2 operational amplifier circuits to match the original dual-channel architecture.

Supply Voltage Range: Substitute parts must support the minimum 2.5V and maximum 5.5V supply voltage span. Parts with extended supply ranges remain compatible provided they operate within this window.

Output Configuration: Rail-to-rail output capability is required to maintain signal swing characteristics of the original design.

Mounting Technology: Surface mount technology is mandatory for manufacturing process alignment.

The three substitute parts identified—LT1215CS8#PBF, TSV992AIDT, and TSV992IYDT—satisfy all mandatory compatibility criteria. Differences in secondary parameters such as slew rate, gain bandwidth product, input bias current, and supply current represent performance variations that do not preclude substitution but require circuit-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

LT1215CS8#PBF (Analog Devices Inc.): This substitute is active and available with 1857 units in stock. It maintains the 50V/µs slew rate matching the original CLC2008ISO8X and provides identical 8-SOIC package compatibility. The extended supply voltage range to 36V offers design flexibility for applications requiring higher supply voltages. However, the operating temperature range is limited to 0°C ~ 70°C, which is narrower than the original -40°C ~ 85°C specification. This part is suitable for commercial temperature range applications where the extended supply voltage capability is beneficial.

TSV992AIDT (STMicroelectronics): This substitute is active with 17568 units in stock and carries AEC-Q100 automotive qualification. It provides extended operating temperature range (-40°C ~ 125°C) and maintains the 2.5V to 5.5V supply voltage span of the original part. The TSV992AIDT features superior input offset voltage (100µV versus 1mV) and extremely low input bias current (1pA). The reduced slew rate (10V/µs versus 50V/µs) and lower gain bandwidth product (20MHz versus 33MHz) represent performance trade-offs that require application-specific evaluation. This part is recommended for automotive-grade applications and designs where low input offset and bias current are critical.

TSV992IYDT (STMicroelectronics): This substitute is active with 1126 units in stock and is functionally identical to the TSV992AIDT, including AEC-Q100 automotive qualification and extended temperature range (-40°C ~ 125°C). Electrical specifications match the TSV992AIDT exactly. Selection between TSV992AIDT and TSV992IYDT depends on packaging format requirements (Cut Tape & Digi-Reel® for both) and inventory availability. Both parts are suitable for automotive applications requiring the same performance profile.

Selection Priority: For applications requiring the closest electrical performance match to the CLC2008ISO8X, the LT1215CS8#PBF is preferred due to matching slew rate. For automotive-grade designs or applications requiring extended temperature operation, the TSV992AIDT or TSV992IYDT are appropriate selections despite lower slew rate and bandwidth specifications.

Frequently Asked Questions (FAQ)

Q: Can the LT1215CS8#PBF be used as a direct replacement for CLC2008ISO8X in all applications?

A: The LT1215CS8#PBF maintains package compatibility and dual-circuit configuration. However, the operating temperature range is limited to 0°C ~ 70°C compared to the original -40°C ~ 85°C. Applications requiring operation below 0°C or above 70°C require alternative substitutes. The extended supply voltage range (up to 36V) is compatible with designs using the original 2.5V to 5.5V range.

Q: What are the key differences between TSV992AIDT and TSV992IYDT?

A: The TSV992AIDT and TSV992IYDT are electrically identical. Both feature AEC-Q100 automotive qualification, extended temperature range (-40°C ~ 125°C), and identical electrical specifications. The parts differ only in packaging format designation and inventory availability. Selection between them is based on supply chain and packaging requirements rather than electrical performance.

Q: How does the reduced slew rate of TSV992 parts affect circuit performance?

A: The TSV992AIDT and TSV992IYDT provide 10V/µs slew rate compared to the original 50V/µs. This reduction affects the maximum rate of output voltage change. Applications with high-frequency signal requirements or fast transient response demands may be affected. Circuit-level analysis is required to determine if the lower slew rate is acceptable for specific use cases.

Q: Are all substitute parts RoHS compliant?

A: The LT1215CS8#PBF is ROHS3 compliant. Both TSV992AIDT and TSV992IYDT are ROHS3 compliant. All three substitutes meet RoHS requirements for new designs.

Q: What is the significance of AEC-Q100 qualification on the TSV992 parts?

A: AEC-Q100 qualification indicates the parts meet automotive industry reliability and quality standards. This qualification is relevant only for applications requiring automotive-grade components. Commercial applications do not require this qualification.

Q: Can supply current differences affect circuit design?

A: The CLC2008ISO8X draws 505µA total supply current (x2 channels). The LT1215CS8#PBF draws 4750µA, while TSV992AIDT and TSV992IYDT draw 820µA. Higher supply current increases power dissipation and thermal load. Power supply design and thermal management may require adjustment when substituting parts with significantly different supply current specifications.

Q: Is the 8-SOIC package identical across all parts?

A: All parts use the 8-SOIC (0.154", 3.90mm Width) package. PCB footprints and assembly processes are compatible across all substitutes without modification.
