Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC2005IMP8MTR is determined by the following critical parameters:

Functional Requirements:

• Dual-channel amplifier configuration (2 circuits)
• Rail-to-rail output capability
• Surface mount packaging in 8-pin format

Electrical Compatibility Criteria:

• Supply voltage range: 2.5 V to 5.5 V (must encompass or match the original specification)
• Operating temperature range: must support -40°C to 85°C minimum
• Output current capability: minimum 55 mA per channel
• Input bias current and offset voltage within acceptable design tolerances

Package Compatibility:

• 8-pin surface mount package (8-SOIC or 8-MSOP variants acceptable for PCB layout re-evaluation)

The OPA2356AIDR from Texas Instruments satisfies these substitution criteria through equivalent dual-channel architecture, matching supply voltage specifications, and superior electrical performance characteristics while maintaining surface mount compatibility.

Engineering Selection Recommendations

Product Status Consideration: The CLC2005IMP8MTR is classified as obsolete, indicating discontinued manufacturing and limited availability. The OPA2356AIDR maintains active product status with Texas Instruments, ensuring ongoing supply chain access and manufacturing support.

Compliance and Certification: The OPA2356AIDR is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for new designs and production. The original CLC2005IMP8MTR lacks documented compliance certifications in the provided specifications.

Electrical Performance: The OPA2356AIDR provides enhanced electrical characteristics including higher slew rate (360 V/µs versus 145 V/µs), increased output current capability (100 mA versus 55 mA per channel), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). These improvements support broader application requirements without compromising compatibility with the original 2.5 V to 5.5 V supply specification.

Package Consideration: The substitute part uses 8-SOIC packaging (0.154", 3.90mm width) compared to the original 8-MSOP (0.118", 3.00mm width). PCB layout modification is required to accommodate the different package footprint and pin spacing.

Frequently Asked Questions (FAQ)

Q: Can the OPA2356AIDR directly replace the CLC2005IMP8MTR without PCB modifications?

A: No. While both devices are 8-pin surface mount dual-channel amplifiers, the package types differ. The CLC2005IMP8MTR uses 8-MSOP (3.00mm width) and the OPA2356AIDR uses 8-SOIC (3.90mm width). PCB footprint redesign is necessary. Pin-to-pin functional compatibility exists for amplifier operation.

Q: What are the key electrical differences between these devices?

A: The OPA2356AIDR offers superior performance: 360 V/µs slew rate (versus 145 V/µs), 100 mA output current per channel (versus 55 mA), and extended temperature range to 125°C (versus 85°C). Input bias current is significantly lower at 3 pA (versus 3 µA). Supply voltage range remains identical at 2.5 V to 5.5 V.

Q: Are the supply voltage requirements compatible?

A: Yes. Both devices operate across the identical supply voltage range of 2.5 V to 5.5 V. No power supply modifications are required for substitution.

Q: What is the impact of higher supply current in the OPA2356AIDR?

A: The OPA2356AIDR draws 8.3 mA (per 2 channels) compared to 4.2 mA for the CLC2005IMP8MTR. Power supply design must accommodate this increased current draw. For battery-powered or low-power applications, this difference may require evaluation.

Q: Is the OPA2356AIDR suitable for the full operating temperature range of the original design?

A: Yes. The OPA2356AIDR supports -40°C to 125°C, which exceeds the original -40°C to 85°C requirement. Applications limited to the original temperature range operate within the substitute device's specifications.

Q: What is the significance of the lower input bias current in the OPA2356AIDR?

A: The OPA2356AIDR input bias current of 3 pA (picoamperes) is substantially lower than the CLC2005IMP8MTR at 3 µA (microamperes). This reduces input impedance loading effects and improves performance in high-impedance signal source applications.

Q: Are there compliance or regulatory advantages to using the OPA2356AIDR?

A: Yes. The OPA2356AIDR is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The obsolete CLC2005IMP8MTR lacks current compliance documentation, making the substitute preferable for new production and long-term supply assurance.
