Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC1009ISO8X 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 direct PCB footprint compatibility without layout redesign.

Functional Classification: The CLC1009ISO8X operates as a voltage feedback amplifier with single-circuit configuration. Substitute parts must maintain this amplifier topology classification.

Electrical Performance Envelope: Substitutes must support the required gain bandwidth product (20 MHz) and slew rate (27 V/µs) to maintain signal fidelity in the target application bandwidth.

Supply Voltage Range: The CLC1009ISO8X operates across 2.5 V to 5.5 V supply span. Substitute parts must accommodate this voltage range or provide compatible operation within system constraints.

Output Drive Capability: The 8.5 mA output current per channel establishes the minimum load-driving requirement for functional equivalence.

Temperature Operating Range: The -40°C to 85°C operating window must be met or exceeded by substitute devices to ensure reliability across specified environmental conditions.

Parameter Comparison

Engineering Selection Recommendations

OPA604AU as Primary Substitute:

The OPA604AU from Texas Instruments is identified as the manufacturer-recommended substitute for the CLC1009ISO8X. Both devices share identical 8-SOIC package geometry, enabling direct PCB footprint compatibility without layout modification.

Electrical Compatibility:

The OPA604AU matches the 20 MHz gain bandwidth product specification of the CLC1009ISO8X. The slew rate of 25 V/µs on the OPA604AU is marginally lower than the 27 V/µs of the original part; this 7.4% difference remains within typical design margins for most signal conditioning applications.

Supply Voltage Consideration:

The OPA604AU operates across a 9 V to 48 V supply range, which does not overlap with the CLC1009ISO8X minimum supply voltage of 2.5 V. Applications requiring operation below 9 V supply voltage cannot use the OPA604AU without circuit redesign. Systems operating at 9 V or higher supply voltage are compatible with the OPA604AU.

Output Current Capability:

The OPA604AU provides 35 mA output current per channel, exceeding the 8.5 mA specification of the CLC1009ISO8X. This enhanced drive capability provides additional design margin for load-driving applications.

Temperature Range:

The OPA604AU operates across -25°C to 85°C, which covers the upper portion of the CLC1009ISO8X temperature range (-40°C to 85°C). Applications requiring operation below -25°C must verify alternative solutions.

Product Status and Compliance:

The OPA604AU is classified as Active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory compliance for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the OPA604AU be used as a direct replacement for the CLC1009ISO8X in all applications?

A: Direct substitution is possible only when the application supply voltage is 9 V or higher and the operating temperature range does not require operation below -25°C. The identical 8-SOIC package enables PCB footprint compatibility without layout changes. Applications with lower supply voltage requirements or extended low-temperature operation require alternative solutions.

Q: What is the significance of the supply voltage range difference between these parts?

A: The CLC1009ISO8X operates at 2.5 V to 5.5 V, while the OPA604AU requires 9 V to 48 V minimum. This represents a fundamental difference in power supply architecture. Low-voltage battery-powered systems or 5 V logic-level applications cannot use the OPA604AU without external voltage regulation or alternative component selection.

Q: Are there performance differences in gain bandwidth product between the CLC1009ISO8X and OPA604AU?

A: Both devices specify 20 MHz gain bandwidth product, ensuring equivalent frequency response characteristics. The slew rate differs by 2 V/µs (27 V/µs versus 25 V/µs), representing a 7.4% reduction. This difference is typically negligible for general-purpose signal conditioning but may require verification in high-speed transient applications.

Q: What does the obsolete status of the CLC1009ISO8X mean for system support?

A: Obsolete status indicates that MaxLinear, Inc. has discontinued manufacturing and will not produce additional units. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. New designs should transition to active-status alternatives such as the OPA604AU to ensure production continuity and future availability.

Q: How do input bias current specifications compare between these amplifiers?

A: The CLC1009ISO8X specifies 370 nA input bias current, while the OPA604AU specifies 5 pA. The OPA604AU exhibits significantly lower input bias current, approximately 74,000 times lower. This improvement reduces input offset drift and is advantageous for high-impedance signal sources and precision measurement applications.

Q: Is the 8-SOIC package identical between both parts?

A: Yes. Both the CLC1009ISO8X and OPA604AU use the 8-SOIC package with 0.154" (3.90mm) width specification. PCB footprints are mechanically and electrically compatible, allowing component substitution without layout redesign or rework.

Q: What compliance certifications should be verified for new production?

A: The OPA604AU carries ROHS3 compliance and REACH unaffected designation. These certifications confirm compliance with European Union environmental and hazardous substance restrictions. Verification of these certifications is required for products destined for regulated markets.
