CLC2050ISO8X Equivalent & Substitute Parts

Part Overview

The CLC2050ISO8X is a voltage feedback amplifier integrated circuit manufactured by MaxLinear, Inc., featuring two independent circuits in an 8-SOIC surface mount package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support, production continuity, and system maintenance.

The CLC2050ISO8X operates across a wide supply voltage range of 3V to 36V with a slew rate of 0.285V/µs and a gain bandwidth product of 330 kHz. With two circuits per package, low input bias current of 20 nA, and output capability of 40 mA per channel, this amplifier is suitable for general-purpose signal conditioning and buffering applications.

Due to its obsolete status, engineers must identify active alternative components that maintain functional compatibility while meeting current design and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC2050ISO8X is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC surface mount package with identical 0.154" (3.90mm) width to ensure PCB footprint compatibility without layout redesign.

Circuit Count: The main part contains 2 independent circuits. Substitute parts must provide at least 2 circuits per package to maintain the same component density and pin configuration.

Supply Voltage Range: The original part operates from 3V to 36V. Substitute parts must support the minimum and maximum supply voltages required by the application. Parts with narrower supply ranges may be suitable only for applications operating within their specified limits.

Amplifier Architecture: The CLC2050ISO8X uses voltage feedback topology. Substitute parts may employ alternative topologies (such as CMOS rail-to-rail) provided they deliver equivalent functional performance in the target application.

Performance Parameters: Slew rate, bandwidth, input bias current, input offset voltage, and output current capability determine suitability for specific signal conditioning tasks. Higher performance specifications generally indicate broader application compatibility.

Product Status and Compliance: Active substitute parts with current RoHS3 compliance and REACH status are preferred for new designs and long-term production support.

Engineering Selection Recommendations

THS4082IDR (Texas Instruments) is the manufacturer-recommended primary substitute for the CLC2050ISO8X. This part is active, RoHS3 compliant, and REACH unaffected, ensuring compliance with current regulatory requirements. The THS4082IDR maintains the same 8-SOIC package and dual-circuit configuration. However, the supply voltage range (10V to 30V minimum) is narrower than the original part, restricting use in applications requiring operation below 10V or above 30V. The THS4082IDR delivers significantly higher performance with a slew rate of 230V/µs and -3dB bandwidth of 175 MHz, making it suitable for higher-speed signal conditioning applications.

TSV622IDT (STMicroelectronics) is an alternative substitute employing CMOS rail-to-rail amplifier architecture. This part is active, RoHS3 compliant, and REACH unaffected. The TSV622IDT offers the lowest supply current (29µA) and lowest input bias current (1 pA), making it ideal for ultra-low-power applications. The supply voltage range (1.5V to 5.5V) is significantly narrower than the original part and is suitable only for low-voltage applications. The TSV622IDT provides extended operating temperature range (-40°C to 125°C) compared to the original part. The slew rate (0.14V/µs) is lower than the original, and the gain bandwidth product (420 kHz) is comparable.

Selection Criteria:

• For applications requiring wide supply voltage operation (3V to 36V), neither substitute fully replaces the original part's voltage range. Application-specific voltage requirements must be evaluated.
• For high-speed applications, THS4082IDR is preferred due to superior bandwidth and slew rate.
• For ultra-low-power applications with supply voltages below 5.5V, TSV622IDT is preferred due to minimal supply current and input bias current.
• Both substitutes are active products with current compliance certifications, ensuring long-term availability and design support.

Frequently Asked Questions (FAQ)

Q: Can the THS4082IDR directly replace the CLC2050ISO8X in all applications?

A: The THS4082IDR shares the same 8-SOIC package and dual-circuit configuration, enabling direct PCB footprint compatibility. However, the supply voltage range differs: THS4082IDR operates from 10V to 30V, while the original part operates from 3V to 36V. Applications requiring supply voltages below 10V or above 30V cannot use the THS4082IDR without circuit redesign.

Q: What is the primary advantage of the TSV622IDT substitute?

A: The TSV622IDT is a CMOS rail-to-rail amplifier with extremely low supply current (29µA) and input bias current (1 pA), making it ideal for battery-powered and ultra-low-power applications. It also provides extended operating temperature range (-40°C to 125°C). The trade-off is a narrower supply voltage range (1.5V to 5.5V) and lower slew rate (0.14V/µs).

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both THS4082IDR and TSV622IDT are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for new designs and production.

Q: Can I use the TSV622IDT in a 36V supply application?

A: No. The TSV622IDT maximum supply voltage is 5.5V. Using this part in a 36V application will cause device failure. The supply voltage must be verified against the application requirements before part selection.

Q: What is the key difference between voltage feedback and CMOS amplifier topologies?

A: The CLC2050ISO8X uses voltage feedback topology, while the TSV622IDT uses CMOS rail-to-rail topology. Both are voltage feedback amplifiers in functional terms. The CMOS architecture of the TSV622IDT provides lower power consumption and lower input bias current, but operates over a narrower supply voltage range.

Q: Do both substitutes maintain the same pin configuration as the original part?

A: Yes. Both THS4082IDR and TSV622IDT use the 8-SOIC package with identical pin spacing (0.154" width, 3.90mm). PCB footprints are directly compatible without modification.

Q: Which substitute should I select for a new design?

A: For new designs, select based on application requirements: THS4082IDR for higher-speed applications with supply voltages between 10V and 30V; TSV622IDT for ultra-low-power applications with supply voltages between 1.5V and 5.5V. Both are active products with long-term availability and support.
