TSV612ID Equivalent & Substitute Parts

Part Overview

The TSV612ID is a CMOS amplifier integrated circuit manufactured by STMicroelectronics, configured as a 2-circuit rail-to-rail operational amplifier in an 8-SOIC surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability for new designs. The TSV612ID operates across a supply voltage range of 1.5V to 5.5V with low input bias current and moderate bandwidth characteristics suitable for low-power analog signal conditioning applications.

Due to its obsolete status, equivalent and substitute parts are necessary for ongoing production support, design continuity, and component procurement. Active alternatives with compatible electrical and mechanical specifications enable seamless integration into existing circuit designs while maintaining functional performance.

Engineering Selection Recommendations

For Direct Replacement (CMOS Topology Preservation)

The AD8602 series (AD8602ARZ, AD8602ARZ-REEL, AD8602ARZ-REEL7, AD8602DRZ, AD8602DRZ-REEL, AD8602DRZ-REEL7, AD8602WARZ-R7) provides direct functional equivalence to the TSV612ID. All variants maintain CMOS amplifier topology, dual-circuit configuration, rail-to-rail output, and 8-SOIC packaging. These parts are manufactured by Analog Devices Inc. and carry Active product status, ensuring long-term availability and production support. All AD8602 variants are RoHS3 compliant with MSL 1 rating, matching the TSV612ID compliance profile.

The AD8602 series operates across a minimum supply voltage of 2.7V, which is higher than the TSV612ID minimum of 1.5V. Applications requiring operation below 2.7V supply voltage cannot use AD8602 substitutes. The maximum supply voltage of 5.5V is identical to the TSV612ID, and the operating temperature range extends to 125°C, exceeding the TSV612ID specification of 85°C.

Packaging variants within the AD8602 series differ only in tape and reel configuration (Tube, Cut Tape & Digi-Reel, or Tape & Reel). Selection among these variants depends on procurement and assembly requirements rather than electrical performance.

For Functional Alternative (Voltage Feedback Topology)

The AD8062 series (AD8062ARZ, AD8062ARZ-R7, AD8062ARZ-RL) provides functional alternatives with voltage feedback amplifier topology. These parts maintain dual-circuit configuration, rail-to-rail output, and 8-SOIC packaging. All AD8062 variants are manufactured by Analog Devices Inc. with Active product status and RoHS3 compliance.

The AD8062 series operates across a supply voltage range of 2.7V to 8V, encompassing the TSV612ID range of 1.5V to 5.5V. Applications requiring operation below 2.7V supply voltage cannot use AD8062 substitutes. The operating temperature range matches the TSV612ID at -40°C to 85°C.

Voltage feedback topology differs fundamentally from CMOS topology. Circuit-level performance characteristics including gain, bandwidth, slew rate, and input offset voltage differ between the two topologies. Applications sensitive to these performance parameters require detailed circuit analysis before substitution.

Compliance and Regulatory Status

All substitute parts listed maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage practices. REACH status is unaffected for all parts, and ECCN classification remains EAR99 across all substitutes.

Frequently Asked Questions (FAQ)

Q: Can AD8602 parts directly replace TSV612ID in all applications?

A: AD8602 parts provide direct functional replacement for applications operating at supply voltages of 2.7V or higher. Applications requiring operation below 2.7V supply voltage require alternative solutions. Circuit-level performance parameters including slew rate, gain bandwidth product, input offset voltage, and input bias current differ between TSV612ID and AD8602 devices. Applications sensitive to these parameters require verification against specific circuit requirements.

Q: What is the difference between AD8602ARZ, AD8602ARZ-REEL, and AD8602ARZ-REEL7?

A: These part numbers represent identical electrical devices with different packaging and tape/reel configurations. AD8602ARZ is supplied in Tube packaging. AD8602ARZ-REEL7 and AD8602ARZ-REEL are supplied in Cut Tape & Digi-Reel and Tape & Reel configurations respectively. Selection depends on assembly equipment compatibility and procurement preferences. Electrical performance and pinout are identical across all three variants.

Q: Why does the AD8062 series have a higher maximum supply voltage (8V) than TSV612ID (5.5V)?

A: The AD8062 series is designed for broader application flexibility with extended supply voltage range. For applications operating within the TSV612ID range of 1.5V to 5.5V, the AD8062 maximum rating of 8V does not affect circuit operation. The extended rating provides design margin and compatibility with systems using higher supply voltages.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (AD8602 and AD8062 series) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the TSV612ID compliance profile. This ensures compatibility with standard manufacturing processes and environmental regulations.

Q: What is the significance of the TSV612ID being classified as Obsolete?

A: Obsolete classification indicates that STMicroelectronics has discontinued production of the TSV612ID. New inventory is limited, and long-term availability cannot be guaranteed. Substitute parts with Active status ensure continued component availability for production support and design continuity.

Q: Can AD8062 voltage feedback amplifiers replace TSV612ID CMOS amplifiers in all circuits?

A: AD8062 parts provide functional alternatives but operate on different amplifier topology. Voltage feedback amplifiers exhibit different frequency response, slew rate, input impedance, and noise characteristics compared to CMOS amplifiers. Circuit designs optimized for CMOS topology may require modification for voltage feedback topology. Applications with strict performance requirements require detailed circuit analysis and testing before substitution.

Q: What is the minimum supply voltage for AD8602 and AD8062 substitutes?

A: Both AD8602 and AD8062 series have a minimum supply voltage of 2.7V. The TSV612ID operates at a minimum of 1.5V. Applications requiring operation below 2.7V cannot use these substitutes and require alternative solutions.

Q: Are the pinouts identical between TSV612ID and substitute parts?

A: All substitute parts maintain the 8-SOIC package configuration with identical physical dimensions (0.154", 3.90mm width). Pinout compatibility must be verified against specific device datasheets, as amplifier topology differences may result in different pin assignments or functional configurations.
