TSV852AIST Equivalent & Substitute Parts
Part Overview
The TSV852AIST is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring dual circuits in a rail-to-rail configuration. This device is classified as an active product and is qualified to AEC-Q100 automotive standards. The TSV852AIST is packaged in an 8-MiniSO surface-mount package with a supply voltage range of 2.5 V to 5.5 V and an operating temperature range of -40°C to 125°C.
Equivalent and substitute parts are identified when alternative devices meet the core functional requirements: dual-circuit general-purpose amplification, rail-to-rail output capability, compatible package footprints, and overlapping electrical specifications. Substitutes are necessary when the primary part is unavailable, when alternative sourcing is required, or when design flexibility permits selection from multiple qualified suppliers.

Engineering Selection Recommendations
Direct Substitutes (Preferred for Automotive Applications):
The AD8542ARMZ and AD8542ARMZ-REEL from Analog Devices Inc. are the closest functional equivalents to the TSV852AIST. Both devices maintain the full automotive temperature range (-40°C to 125°C), dual-circuit configuration, and rail-to-rail output. The AD8542ARMZ-REEL variant is packaged in Cut Tape & Digi-Reel format, matching the TSV852AIST packaging specification. These parts feature lower input bias current (4 pA) and reduced supply current (45 µA), offering improved performance in low-power applications. Both are RoHS3 compliant with MSL 1 rating.
The LMV342IDGKR and LMV342MM/NOPB from Texas Instruments and National Semiconductor respectively maintain the full automotive temperature range and offer superior output current capability (113 mA per channel). These CMOS variants feature exceptionally low input bias current and are suitable for high-impedance signal sources. The LMV342IDGKR is available in Cut Tape & Digi-Reel packaging.
Compatible Alternatives (Extended Temperature or Reduced Supply Current):
The LMV358IDGKR and LMV358IPW from Texas Instruments are general-purpose amplifiers with identical electrical specifications to the TSV852AIST across the full temperature range. The LMV358IDGKR is available in 8-VSSOP package with Cut Tape & Digi-Reel packaging. The LMV358IPW is packaged in 8-TSSOP but carries a Last Time Buy status, indicating limited future availability.
The AZV358MMTR-G1 from Diodes Incorporated meets core electrical requirements but operates only to 85°C maximum, restricting use in applications requiring the full -40°C to 125°C range. This device is available in high inventory (98,100 pcs) and offers cost-effective sourcing for temperature-limited designs.
Limited Substitutes (Reduced Performance or Restricted Temperature Range):
The BU7242FVM-TR and BU7242SFVM-TR from Rohm Semiconductor are CMOS amplifiers with reduced slew rate (0.4 V/µs) and gain bandwidth product (900 kHz), limiting suitability for high-speed applications. The BU7242SFVM-TR extends to 105°C but does not reach the full 125°C upper limit. Both devices feature extremely low input bias current (1 pA) and are suitable for ultra-low-power, low-frequency designs.
The LMV358DMR2G from onsemi is a voltage feedback amplifier limited to 85°C maximum operating temperature, restricting automotive qualification scope. This device offers high output current capability (160 mA per channel) and is suitable for applications not requiring extended temperature operation.
Compliance and Certification:
All substitute parts listed maintain RoHS3 compliance and REACH unaffected status. Moisture sensitivity levels range from MSL 1 (unlimited) to MSL 3 (168 hours), with most substitutes rated MSL 1 or MSL 2. Automotive-grade qualification (AEC-Q100) is not explicitly stated for substitute parts; verification with the manufacturer is required for applications demanding automotive certification.
Frequently Asked Questions (FAQ)
Q: Can the AD8542ARMZ directly replace the TSV852AIST in automotive applications?
A: The AD8542ARMZ meets the core electrical and temperature specifications required for automotive use. Both devices feature dual circuits, rail-to-rail output, and operate across -40°C to 125°C. However, automotive qualification status (AEC-Q100) must be confirmed with Analog Devices Inc. for critical safety-related applications. The AD8542ARMZ-REEL variant is recommended due to matching Cut Tape & Digi-Reel packaging.
Q: What is the primary difference between the TSV852AIST and LMV358IDGKR?
A: Both devices are general-purpose dual-circuit amplifiers with identical temperature range (-40°C to 125°C) and rail-to-rail output. The TSV852AIST features a slew rate of 0.7 V/µs and gain bandwidth product of 1.3 MHz, while the LMV358IDGKR offers 1 V/µs slew rate and 1 MHz gain bandwidth product. The LMV358IDGKR provides faster slew rate but lower bandwidth. Package differences exist: TSV852AIST uses 8-MSOP, while LMV358IDGKR uses 8-VSSOP. Both are RoHS3 compliant.
Q: Are CMOS variants (LMV342, BU7242) suitable replacements for the TSV852AIST?
A: CMOS variants offer advantages in low input bias current and low-power operation but may introduce different noise characteristics and offset voltage behavior. The LMV342IDGKR maintains the full automotive temperature range and offers superior output current (113 mA vs. 70 mA). The BU7242 series operates only to 85°C maximum, restricting use in full-range automotive designs. CMOS substitution is acceptable when application requirements permit, but circuit validation is necessary.
Q: Why does the AZV358MMTR-G1 have higher inventory but lower temperature rating?
A: The AZV358MMTR-G1 is limited to -40°C to 85°C operation, excluding it from applications requiring the full -40°C to 125°C automotive range. This restriction reduces demand in automotive markets but increases availability for industrial and consumer applications operating within the 85°C limit. High inventory reflects market positioning for non-automotive segments.
Q: What packaging considerations apply when substituting the TSV852AIST?
A: The TSV852AIST is specified in 8-MSOP (0.118", 3.00mm width) package. Substitute parts use 8-MSOP, 8-VSSOP (0.110", 2.80mm width), or 8-TSSOP (0.173", 4.40mm width) packages. While all are 8-pin surface-mount devices with compatible pinouts, physical footprint differences require PCB layout verification. The 8-VSSOP package is narrower (2.80mm vs. 3.00mm), and the 8-TSSOP is wider (4.40mm), affecting board space allocation. Consult device datasheets for exact pin assignments and thermal characteristics.
Q: Is the LMV358IPW recommended for new designs?
A: The LMV358IPW carries a Last Time Buy status, indicating discontinued production and limited future availability. While electrically equivalent to the TSV852AIST, this device is not recommended for new designs requiring long-term supply assurance. The LMV358IDGKR (Cut Tape & Digi-Reel variant) is the preferred alternative from Texas Instruments for ongoing production.
Q: What is the significance of MSL (Moisture Sensitivity Level) ratings in substitution?
A: Moisture sensitivity level indicates the maximum time a component can be exposed to ambient conditions (30°C, 60% relative humidity) before soldering. MSL 1 (unlimited) allows indefinite storage without special handling. MSL 2 (1 year) and MSL 3 (168 hours) require controlled storage and baking before reflow soldering. The TSV852AIST and most substitutes are rated MSL 1, simplifying supply chain management. The LMV358IDGKR is rated MSL 2, requiring standard moisture control procedures.
Q: Can supply current differences affect circuit design when substituting parts?
A: Yes. The TSV852AIST draws 130 µA (x2 channels), while the AD8542ARMZ draws only 45 µA, and the LMV358IDGKR draws 210 µA. Lower supply current (AD8542ARMZ) reduces power dissipation and heat generation, beneficial for battery-powered or thermally constrained designs. Higher supply current (LMV358IDGKR) may require larger power supply capacity and thermal management. Power supply design and thermal analysis must be re-evaluated when substituting parts with significantly different supply current specifications.
