Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC1005ISO8 is determined by strict alignment of electrical and mechanical parameters within the voltage feedback amplifier category. The following criteria establish substitution validity:

Primary Substitution Criteria:

• Amplifier topology: Voltage feedback architecture
• Circuit count: Single circuit configuration
• Output stage: Rail-to-rail output capability
• Package form factor: 8-SOIC surface mount package with 3.90mm width
• Operating temperature range: Minimum -40°C to maximum 85°C coverage
• Supply voltage compatibility: Substitute must operate within or exceed the 2.5V to 5.5V range

Secondary Electrical Parameters:

• Slew rate: Substitute value must equal or exceed 145V/µs
• Gain bandwidth product: Substitute value must equal or exceed 90 MHz
• Input bias current: Lower values acceptable (improved performance)
• Input offset voltage: Values at or below 1.4 mV acceptable
• Supply current: Values at or below 4.2 mA acceptable
• Output current capability: Values at or above 55 mA acceptable

The LMH6639MA/NOPB from Texas Instruments satisfies all primary and secondary substitution criteria and is classified as a direct functional equivalent.

Engineering Selection Recommendations

Product Status Consideration: The CLC1005ISO8 is classified as obsolete. The LMH6639MA/NOPB is classified as active product status, ensuring ongoing manufacturer support, availability, and compliance with current industry standards.

Compliance and Certification: The LMH6639MA/NOPB carries REACH Unaffected status and EAR99 export classification, supporting regulatory compliance requirements for commercial and industrial applications. The CLC1005ISO8 is marked as OBSOLETE in export classification.

Electrical Performance: The LMH6639MA/NOPB demonstrates equivalent or superior performance across all measured electrical parameters. Slew rate increases from 145V/µs to 200V/µs, -3dB bandwidth extends from 90 MHz to 228 MHz, and output current capability doubles from 55 mA to 112 mA. Input bias current improves by approximately 2000 times (3 µA to 1.4 nA), and input offset voltage decreases marginally from 1.4 mV to 1.3 mV.

Supply Voltage Range: The LMH6639MA/NOPB minimum supply voltage is 3V versus 2.5V for the CLC1005ISO8. Applications operating at 2.5V supply voltage require verification of circuit design compatibility. Maximum supply voltage extends to 12V, providing greater design flexibility.

Package and Mechanical Compatibility: Both components utilize identical 8-SOIC surface mount packaging with 3.90mm width, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the LMH6639MA/NOPB directly replace the CLC1005ISO8 in existing designs?

A: Direct replacement is possible for applications operating at supply voltages of 3V or higher. The LMH6639MA/NOPB requires minimum 3V supply voltage compared to the CLC1005ISO8 minimum of 2.5V. PCB footprints are identical (8-SOIC), and all electrical performance parameters are equivalent or superior. Applications using 2.5V supply voltage require circuit redesign or alternative component selection.

Q: What are the key electrical advantages of the LMH6639MA/NOPB?

A: The LMH6639MA/NOPB provides improved slew rate (200V/µs versus 145V/µs), extended bandwidth (-3dB bandwidth of 228 MHz versus 90 MHz), doubled output current capability (112 mA versus 55 mA), and significantly reduced input bias current (1.4 nA versus 3 µA). These improvements enhance signal fidelity, output drive capability, and input impedance characteristics.

Q: Are there packaging differences between these components?

A: Both components are supplied in 8-SOIC surface mount packages with identical 0.154-inch (3.90mm) width. Moisture sensitivity level is identical at MSL 1 (Unlimited). No packaging modifications are required for substitution.

Q: What is the supply voltage compatibility consideration?

A: The CLC1005ISO8 operates from 2.5V to 5.5V. The LMH6639MA/NOPB operates from 3V to 12V. Designs operating at 2.5V supply voltage cannot use the LMH6639MA/NOPB without circuit modification. Designs operating at 3V or higher supply voltage are fully compatible.

Q: Why is the CLC1005ISO8 marked as obsolete?

A: The CLC1005ISO8 has reached end-of-life status with MaxLinear, Inc. No new production is scheduled. The LMH6639MA/NOPB is an active product from Texas Instruments with ongoing manufacturer support and availability.

Q: Are there regulatory or compliance differences?

A: The LMH6639MA/NOPB carries REACH Unaffected status and EAR99 export classification. The CLC1005ISO8 is marked as OBSOLETE in export classification. Applications requiring current regulatory compliance should transition to the LMH6639MA/NOPB.

Q: What is the operating temperature range compatibility?

A: Both components operate across identical temperature ranges of -40°C to 85°C. No temperature-related design modifications are required.
