CLC2605ISO8MTR Equivalent & Substitute Parts

Part Overview

The CLC2605ISO8MTR is a current feedback amplifier manufactured by MaxLinear, Inc., configured as a dual-channel operational amplifier in an 8-SOIC surface mount package. This device is classified as obsolete, indicating it is no longer in active production. The high slew rate of 2500V/µs and gain bandwidth product of 1.5 GHz position this component for high-speed signal processing applications. Due to its obsolete status, equivalent substitute parts are necessary for new designs and ongoing production requirements. Substitute devices must maintain compatibility with the 8-SOIC package footprint and support the electrical operating parameters of the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC2605ISO8MTR is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Compatibility Criteria:

• Amplifier Type: Current Feedback (dual-channel configuration)
• Package / Case: 8-SOIC surface mount footprint
• Mounting Type: Surface Mount
• Operating Temperature Range: Minimum -40°C to maximum 85°C
• Voltage Supply Span: Minimum 4.5V to maximum 12V

Performance Parameters for Substitution Assessment:

• Slew Rate: 2500V/µs (original specification)
• Gain Bandwidth Product: 1.5 GHz (original specification)
• -3dB Bandwidth: 1.2 GHz (original specification)
• Current - Output / Channel: 280 mA (original specification)
• Current - Supply: 12mA per channel (original specification)

The substitute parts listed below are qualified as electrical and mechanical equivalents based on their ability to operate within the defined parameter ranges of the CLC2605ISO8MTR. All substitute devices share the 8-SOIC package configuration and dual-channel current feedback amplifier topology. Variations in slew rate, bandwidth, and supply current reflect different performance characteristics within the current feedback amplifier category and must be evaluated against specific application requirements.

Engineering Selection Recommendations

Active Product Status Requirement: All substitute parts listed—AD8008ARZ-REEL, LMH6724MA/NOPB, LMH6724MAX/NOPB, and LT1229CS8#TRPBF—maintain active product status with their respective manufacturers. This ensures ongoing availability, technical support, and compliance with current manufacturing standards.

Compliance and Certification:

• AD8008ARZ-REEL: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• LMH6724MA/NOPB: EAR99 classification
• LMH6724MAX/NOPB: EAR99 classification
• LT1229CS8#TRPBF: ROHS3 Compliant, REACH Unaffected, EAR99 classification

Package and Footprint Compatibility: All substitute devices are housed in 8-SOIC surface mount packages with identical 0.154" (3.90mm) width specifications. This ensures direct PCB footprint compatibility without layout modifications.

Performance Trade-offs: The CLC2605ISO8MTR exhibits the highest slew rate (2500V/µs) and bandwidth (1.2 GHz) among the listed devices. Substitute selection must account for reduced performance in these parameters. The AD8008ARZ-REEL provides the closest performance match with 1000V/µs slew rate and 500 MHz bandwidth. The LMH6724 series offers lower power consumption (1mA per channel versus 12mA) with reduced bandwidth (370 MHz). The LT1229CS8#TRPBF operates at the lowest bandwidth (100 MHz) but supports extended supply voltage range (4V to 30V) and operates at reduced temperature range (0°C to 70°C).

Output Current Capability: The CLC2605ISO8MTR provides 280 mA output current per channel. All substitute devices deliver reduced output current: AD8008ARZ-REEL (130 mA), LMH6724 series (110 mA), and LT1229CS8#TRPBF (125 mA). Applications requiring the full 280 mA output current cannot use these substitutes without external buffering.

Frequently Asked Questions (FAQ)

Q: Can the AD8008ARZ-REEL directly replace the CLC2605ISO8MTR in all applications?

A: The AD8008ARZ-REEL shares the 8-SOIC package footprint and dual-channel current feedback amplifier topology. However, it delivers reduced slew rate (1000V/µs versus 2500V/µs), lower bandwidth (500 MHz versus 1.2 GHz), and reduced output current (130 mA versus 280 mA). Direct substitution is valid only for applications where these reduced performance parameters are acceptable.

Q: What is the primary advantage of the LMH6724MA/NOPB and LMH6724MAX/NOPB substitutes?

A: Both LMH6724 variants offer significantly reduced power consumption (1mA per channel versus 12mA) while maintaining the 8-SOIC package and dual-channel configuration. They are suitable for power-constrained applications where bandwidth requirements do not exceed 370 MHz. The LMH6724MA/NOPB is supplied in bulk packaging, while the LMH6724MAX/NOPB is also available in bulk form.

Q: Why does the LT1229CS8#TRPBF have a different operating temperature range?

A: The LT1229CS8#TRPBF operates from 0°C to 70°C, compared to the CLC2605ISO8MTR range of -40°C to 85°C. This narrower temperature range reflects the device's design specifications. Applications requiring full -40°C to 85°C operation must use AD8008ARZ-REEL, LMH6724MA/NOPB, or LMH6724MAX/NOPB.

Q: Are all substitute parts available in the same packaging format?

A: No. The AD8008ARZ-REEL is supplied in Tape & Reel (TR) format. The LMH6724MA/NOPB and LMH6724MAX/NOPB are supplied in bulk packaging. The LT1229CS8#TRPBF is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly requirements.

Q: What is the impact of reduced output current on circuit design?

A: The CLC2605ISO8MTR provides 280 mA per channel output current. All substitutes deliver 110 mA to 130 mA per channel. Applications requiring higher output current must incorporate external current buffering stages or select alternative amplifier topologies.

Q: Can the LT1229CS8#TRPBF operate at supply voltages above 12V?

A: Yes. The LT1229CS8#TRPBF supports supply voltages from 4V to 30V, exceeding the 12V maximum of the CLC2605ISO8MTR and other substitutes. This extended voltage range is beneficial for applications requiring higher supply voltages, provided the reduced bandwidth (100 MHz) meets application requirements.

Q: How do input offset voltage specifications compare across substitutes?

A: The CLC2605ISO8MTR specifies 10 mV input offset voltage. The AD8008ARZ-REEL provides superior performance at 0.5 mV. The LMH6724 series specifies 1 mV. The LT1229CS8#TRPBF specifies 3 mV. Lower input offset voltage reduces DC error in precision applications.

Q: Are all substitute parts RoHS compliant?

A: The AD8008ARZ-REEL and LT1229CS8#TRPBF are explicitly marked as ROHS3 Compliant. The LMH6724MA/NOPB and LMH6724MAX/NOPB do not include RoHS compliance information in the provided specifications. Verification with the manufacturer is required for applications with RoHS compliance requirements.
