TSV623IST Equivalent & Substitute Parts

Part Overview

The TSV623IST is a CMOS dual-channel operational amplifier manufactured by STMicroelectronics, designed for rail-to-rail signal conditioning applications. This surface-mount linear amplifier operates across a wide supply voltage range of 1.5V to 5.5V and maintains active product status with full RoHS3 compliance. The TSV623IST is packaged in a 10-MiniSO form factor suitable for space-constrained applications requiring low-power operation and precision signal processing.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory constraints, or when enhanced performance characteristics are required for specific application demands while maintaining functional compatibility within the same package class and electrical operating envelope.

Substitute Part Grouping Explanation

Substitute parts for the TSV623IST are qualified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

Dual-channel (2 circuit) configuration
Rail-to-rail output capability
Surface-mount packaging in 10-pin TFSOP/MSOP form factor (0.118", 3.00mm width)
Operating temperature range of -40°C to 125°C or extended to 85°C minimum
Supply voltage compatibility within or overlapping the 1.5V to 5.5V range
RoHS3 compliance and MSL Level 1 rating

Performance Parameter Flexibility: Substitute parts may exhibit variations in slew rate, gain bandwidth product, input bias current, input offset voltage, and supply current. These variations are acceptable when the substitute part maintains the same package footprint, pin configuration, and functional output characteristics (rail-to-rail operation with dual channels).

The following parts meet these substitution criteria: LMV712Q1MM/NOPB, LMV712Q1MMX/NOPB, LMV792MM/NOPB, TLV2763IDGS, and TLV2763IDGSR.

Engineering Selection Recommendations

LMV712Q1MM/NOPB and LMV712Q1MMX/NOPB (Texas Instruments)

These parts are qualified for automotive applications under AEC-Q100 standard and maintain full compatibility with the TSV623IST package footprint. Both variants feature identical electrical specifications with significantly enhanced slew rate (5V/µs) and gain bandwidth product (5 MHz). The LMV712Q1MMX/NOPB variant offers higher inventory availability (7300 units) compared to the standard LMV712Q1MM/NOPB (1689 units). These substitutes are suitable for applications requiring improved dynamic response while maintaining the same thermal and compliance profile. The minimum supply voltage requirement increases to 2.7V, which must be verified against system design specifications.

LMV792MM/NOPB (National Semiconductor)

This part delivers the highest performance metrics among substitutes with slew rate of 11.5V/µs and gain bandwidth product of 17 MHz. The LMV792MM/NOPB operates at the lowest minimum supply voltage (1.8V) and features the lowest input offset voltage (100 µV) and input bias current (0.1 pA). This substitute is appropriate for high-speed signal conditioning applications. RoHS3 compliance and MSL rating are not explicitly specified for this part.

TLV2763IDGS and TLV2763IDGSR (Texas Instruments)

Both TLV2763 variants provide ultra-low power consumption (20 µA supply current) and are optimized for battery-powered and energy-constrained applications. These parts maintain slew rate of 0.23V/µs and gain bandwidth product of 500 kHz, closely matching the TSV623IST performance envelope. The maximum supply voltage is limited to 3.6V, restricting use in systems requiring 5V operation. The TLV2763IDGSR variant in Cut Tape & Digi-Reel packaging offers significantly higher inventory (11246 units) compared to the tube-packaged TLV2763IDGS (5260 units). Operating temperature range is limited to -40°C to 85°C, which must be evaluated for applications requiring 125°C operation.

All substitute parts maintain RoHS3 compliance, MSL Level 1 rating, and active product status where specified. Selection should be based on specific application requirements for supply voltage range, operating temperature, slew rate, and bandwidth characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LMV712Q1MM/NOPB directly replace the TSV623IST in all applications?

A: The LMV712Q1MM/NOPB shares identical package footprint and pin configuration with the TSV623IST, enabling direct physical substitution on PCB layouts. However, the minimum supply voltage requirement increases from 1.5V to 2.7V. Applications operating below 2.7V supply voltage cannot use this substitute. All other electrical parameters are compatible or superior, and automotive AEC-Q100 qualification provides additional reliability assurance.

Q: What is the primary difference between LMV712Q1MM/NOPB and LMV712Q1MMX/NOPB?

A: Both variants are electrically identical with matching specifications. The primary difference is packaging format and inventory availability. The LMV712Q1MM/NOPB is supplied in Tape & Reel format with 1689 units in stock, while the LMV712Q1MMX/NOPB is also in Tape & Reel format with significantly higher inventory of 7300 units. Selection between these variants depends on procurement volume requirements and lead-time considerations.

Q: Why do the TLV2763 variants have a lower maximum supply voltage (3.6V) compared to the TSV623IST (5.5V)?

A: The TLV2763 series is specifically designed for low-voltage, low-power applications typical of battery-powered and portable devices. The 3.6V maximum rating aligns with single-cell lithium-ion battery systems. Applications requiring 5V operation must use alternative substitutes such as the LMV712 series or LMV792MM/NOPB, which support the full 5.5V maximum supply voltage.

Q: Is the LMV792MM/NOPB suitable for all TSV623IST applications?

A: The LMV792MM/NOPB offers superior performance characteristics including higher slew rate (11.5V/µs), wider gain bandwidth product (17 MHz), and lower input offset voltage (100 µV). These enhancements make it suitable for high-speed and precision applications. However, RoHS3 compliance and MSL rating are not explicitly specified for this part. Verification of compliance status with your procurement and quality requirements is necessary before selection.

Q: What is the impact of operating temperature range differences on part selection?

A: The TSV623IST, LMV712Q1MM/NOPB, and LMV712Q1MMX/NOPB support -40°C to 125°C operation. The TLV2763IDGS and TLV2763IDGSR variants are limited to -40°C to 85°C. Applications requiring operation above 85°C must use the TSV623IST or LMV712 series. The LMV792MM/NOPB also supports -40°C to 125°C operation.

Q: Can I use the TLV2763IDGSR instead of TLV2763IDGS for the same application?

A: Yes. Both variants are electrically identical and share the same 10-TFSOP/10-MSOP package footprint. The primary difference is packaging format: TLV2763IDGS is supplied in Tube packaging (5260 units available), while TLV2763IDGSR is supplied in Cut Tape & Digi-Reel format (11246 units available). Selection depends on your assembly process requirements and inventory needs.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) dual-channel configuration, (2) rail-to-rail output capability, (3) identical 10-pin TFSOP/MSOP package footprint, (4) overlapping or compatible supply voltage ranges, (5) operating temperature range meeting or exceeding application requirements, and (6) compliance certifications (RoHS3, MSL Level 1) matching procurement specifications. Performance parameters such as slew rate and gain bandwidth product may vary between substitutes based on application demands.

Q: Is the TSV623IST CMOS architecture critical for my application, or can I use General Purpose amplifier substitutes?

A: The substitute parts listed (LMV712, LMV792, TLV2763) are classified as General Purpose amplifiers rather than CMOS-specific designs. However, all maintain rail-to-rail output, dual-channel configuration, and compatible package specifications. The functional performance differences relate to slew rate, bandwidth, and power consumption rather than amplifier architecture. Verify that the specific performance characteristics of your chosen substitute meet your application's signal conditioning requirements.
