TSV6293AIST Equivalent & Substitute Parts
Part Overview
The TSV6293AIST is an active, production-status CMOS amplifier manufactured by STMicroelectronics. This dual-circuit, rail-to-rail operational amplifier is designed for low-power applications requiring minimal input bias current and operates across an extended temperature range of -40°C to 125°C. The device is packaged in a 10-MiniSO surface-mount configuration and is RoHS3 compliant with unlimited moisture sensitivity rating.
Equivalent and substitute parts are identified based on matching functional requirements: dual-circuit configuration, rail-to-rail output capability, compatible package footprints, overlapping supply voltage ranges, and operating temperature specifications. Substitutes must maintain electrical compatibility within the application's design constraints.

Substitute Part Grouping Explanation
Substitute parts for the TSV6293AIST are selected based on the following electrical and mechanical compatibility criteria:
Primary Matching Criteria:
- Dual-circuit (2 amplifier) configuration
- Rail-to-rail output capability
- Surface-mount packaging with compatible footprint (10-MSOP, 10-TFSOP, or 10-VSSOP)
- Operating temperature range of -40°C to 125°C
- Supply voltage span overlap with 1.5V minimum and 5.5V maximum
- Active product status
Electrical Performance Considerations: Substitute parts are grouped by their slew rate, gain bandwidth product, input bias current, and output current capabilities. While the TSV6293AIST operates at lower performance levels (0.5V/µs slew rate, 1.3 MHz gain bandwidth), substitute parts with higher performance specifications remain functionally compatible in applications where the TSV6293AIST's performance envelope is not exceeded.
Package Compatibility: All substitute parts utilize 10-pin surface-mount packages (10-MSOP or 10-VSSOP variants) with identical 0.118" (3.00mm) width, ensuring PCB footprint compatibility.

Engineering Selection Recommendations
Full Compatibility Substitutes:
The AD8647ARMZ and AD8647ARMZ-REEL (Analog Devices Inc.) provide direct functional substitution with extended performance specifications. Both variants maintain the full operating temperature range of -40°C to 125°C, matching the TSV6293AIST. These parts are active products with RoHS3 compliance and REACH unaffected status. The AD8647ARMZ-REEL variant is supplied in Tape & Reel packaging, identical to the TSV6293AIST, facilitating seamless integration into automated assembly processes.
The LMV712Q1MM/NOPB and LMV712Q1MMX/NOPB (Texas Instruments) are automotive-grade alternatives qualified to AEC-Q100 standards. Both maintain the full -40°C to 125°C operating temperature range and are supplied in Tape & Reel packaging. These parts are suitable for applications requiring automotive qualification.
The LMV792MM/NOPB (National Semiconductor) operates across the extended temperature range of -40°C to 125°C and provides superior performance characteristics with minimal input offset voltage (100 µV) and input bias current (0.1 pA). This part is active and RoHS3 compliant.
Limited Compatibility Substitute:
The AD8592ARMZ-REEL (Analog Devices Inc.) operates only to 85°C maximum, restricting its use to applications where the full -40°C to 125°C range is not required. This part is supplied in Cut Tape & Digi-Reel® packaging rather than standard Tape & Reel. It remains RoHS3 compliant and active.
Supply Voltage Consideration:
The TSV6293AIST supports operation at 1.5V minimum supply voltage. The AD8592ARMZ-REEL requires 2.5V minimum, and the AD8647 variants require 2.7V minimum. The LMV712 variants require 2.7V minimum. The LMV792MM/NOPB supports 1.8V minimum, providing the closest match to the TSV6293AIST's lower supply voltage capability.
Frequently Asked Questions (FAQ)
Q: Can the AD8647ARMZ directly replace the TSV6293AIST on an existing PCB?
A: Yes. Both parts use identical 10-pin surface-mount packages (10-MSOP) with 0.118" (3.00mm) width, ensuring PCB footprint compatibility. Pin assignments must be verified against device datasheets to confirm functional equivalence in the specific application circuit.
Q: What is the primary difference between AD8647ARMZ and AD8647ARMZ-REEL?
A: Both parts are electrically identical. The difference is packaging format: AD8647ARMZ is supplied in Tube packaging, while AD8647ARMZ-REEL is supplied in Tape & Reel (TR) format. For high-volume automated assembly, the Tape & Reel variant is standard.
Q: Why does the AD8592ARMZ-REEL have a lower maximum operating temperature than the TSV6293AIST?
A: The AD8592ARMZ-REEL is specified for operation to 85°C maximum, while the TSV6293AIST operates to 125°C. This part is suitable only for applications where the full extended temperature range is not required.
Q: Are the LMV712Q1MM/NOPB and LMV712Q1MMX/NOPB interchangeable?
A: Yes. Both parts are electrically and mechanically identical. The difference is in qualification and traceability documentation. Both are automotive-grade (AEC-Q100 qualified) and operate across -40°C to 125°C.
Q: What is the significance of the "Q1" designation in the LMV712Q1 part numbers?
A: The "Q1" designation indicates automotive-grade qualification to AEC-Q100 standards. These parts are suitable for automotive applications requiring specific reliability and qualification documentation.
Q: Does the LMV792MM/NOPB require different PCB layout considerations compared to the TSV6293AIST?
A: Both parts use identical 10-pin surface-mount packages with matching footprints. PCB layout considerations are determined by application circuit requirements rather than package differences. Decoupling capacitor placement and trace routing should follow the specific application's design guidelines.
Q: Can I use the LMV792MM/NOPB in a 1.5V supply application?
A: The LMV792MM/NOPB supports 1.8V minimum supply voltage, which is higher than the TSV6293AIST's 1.5V minimum. For applications requiring 1.5V operation, the TSV6293AIST or equivalent parts supporting 1.5V minimum must be used.
Q: What is the difference between 10-MSOP and 10-VSSOP packages?
A: Both are 10-pin surface-mount packages with identical 0.118" (3.00mm) width and footprint compatibility. MSOP and VSSOP designations refer to manufacturer-specific package naming conventions but are mechanically and electrically equivalent for these amplifier applications.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the TSV6293AIST's environmental compliance status.
Q: Which substitute part offers the lowest input offset voltage?
A: The LMV792MM/NOPB provides the lowest input offset voltage at 100 µV, compared to the TSV6293AIST's 1 mV specification.
