TSV633IST Equivalent & Substitute Parts

Part Overview

The TSV633IST is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring dual circuits in a 10-MiniSO surface-mount package. This device is classified as an active product with automotive-grade qualification (AEC-Q100) and operates across a supply voltage range of 1.5 V to 5.5 V with rail-to-rail output capability. The TSV633IST is designed for low-power applications requiring dual-channel amplification in compact form factors.

Substitute parts become necessary when the original component experiences supply constraints, extended lead times, or when design requirements permit operation within alternative electrical specifications while maintaining functional compatibility and package-level interchangeability.

Engineering Selection Recommendations

Automotive-Grade Applications (AEC-Q100 Required):

The LMV712Q1MM/NOPB and LMV712Q1MMX/NOPB are direct automotive-qualified substitutes for the TSV633IST. Both devices carry AEC-Q100 qualification and automotive-grade designation, matching the original part's compliance profile. These parts operate across the full temperature range (-40°C to 125°C) and maintain the 5.5 V maximum supply voltage specification. The LMV712 series exhibits higher slew rate (5 V/µs) and gain bandwidth product (5 MHz) compared to the TSV633IST baseline, with improved input offset voltage (400 µV). Current supply requirements increase to 1.22 mA per channel. These substitutes are suitable for automotive applications where AEC-Q100 compliance is mandatory.

General Industrial and Consumer Applications (Non-Automotive):

The AD8592ARMZ-REEL, MAX9917EUB+, and MAX9917EUB+T are suitable for non-automotive applications. The AD8592ARMZ-REEL provides higher output current capability (250 mA per channel) and operates to 6 V maximum supply voltage, though the operating temperature range is limited to -40°C to 85°C. The MAX9917 series (both EUB+ and EUB+T variants) offers the lowest supply current (40 µA per channel) and operates across 1.8 V to 5.5 V supply range, making these parts suitable for ultra-low-power applications. However, the MAX9917 series is limited to -40°C to 85°C operating temperature and provides lower output current (15 mA per channel).

High-Performance Applications:

The LMV792MM/NOPB delivers the highest slew rate (11.5 V/µs) and gain bandwidth product (17 MHz) among all substitutes, with the lowest input bias current (0.1 pA) and input offset voltage (100 µV). This device operates across the full temperature range (-40°C to 125°C) and supports the 1.5 V minimum supply voltage specification. The LMV792MM/NOPB is appropriate for applications requiring superior dynamic performance and precision characteristics.

Supply Voltage Compatibility:

All substitute parts support the 5.5 V maximum supply voltage of the TSV633IST. The LMV792MM/NOPB uniquely supports the 1.5 V minimum supply voltage specification. The LMV712 series supports 2.7 V minimum, while the AD8592ARMZ-REEL requires 2.5 V minimum and the MAX9917 series requires 1.8 V minimum. Design applications operating below 2.5 V must employ either the TSV633IST, LMV792MM/NOPB, or MAX9917 series.

Temperature Range Considerations:

Applications requiring operation across the full -40°C to 125°C temperature range are limited to the TSV633IST, LMV712Q1MM/NOPB, LMV712Q1MMX/NOPB, and LMV792MM/NOPB. The AD8592ARMZ-REEL, MAX9917EUB+, and MAX9917EUB+T are restricted to -40°C to 85°C operation.

Frequently Asked Questions (FAQ)

Q: Can the MAX9917EUB+ be used as a direct replacement for the TSV633IST in automotive applications?

A: No. The MAX9917EUB+ is not automotive-qualified and lacks AEC-Q100 certification. Additionally, its operating temperature range is limited to -40°C to 85°C, which does not cover the full -40°C to 125°C specification of the TSV633IST. The MAX9917EUB+ is suitable only for non-automotive applications operating within the -40°C to 85°C temperature window.

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

A: Both parts are electrically identical and carry identical specifications. The difference lies in packaging designation: LMV712Q1MM/NOPB is supplied in Tape & Reel format, while LMV712Q1MMX/NOPB is also supplied in Tape & Reel format. Both are automotive-qualified with AEC-Q100 certification and operate across -40°C to 125°C.

Q: Is the AD8592ARMZ-REEL compatible with the TSV633IST in terms of package footprint?

A: Yes. The AD8592ARMZ-REEL uses the 10-MSOP package with 0.118" (3.00mm) width, which is mechanically compatible with the TSV633IST's 10-MiniSO package footprint. However, the AD8592ARMZ-REEL is not automotive-qualified and operates only to 85°C maximum temperature.

Q: Which substitute part offers the lowest power consumption?

A: The MAX9917EUB+ and MAX9917EUB+T both offer the lowest supply current at 40 µA per channel (80 µA total for dual channels), compared to the TSV633IST baseline of 50 µA per channel (100 µA total). These parts are suitable for ultra-low-power applications but are limited to -40°C to 85°C operation and lack automotive qualification.

Q: Can the LMV792MM/NOPB operate at the 1.5 V minimum supply voltage of the TSV633IST?

A: Yes. The LMV792MM/NOPB supports a minimum supply voltage of 1.8 V, which is higher than the TSV633IST's 1.5 V minimum. However, the LMV792MM/NOPB is the only substitute part capable of operating at 1.5 V supply voltage. For applications requiring 1.5 V operation, the TSV633IST or LMV792MM/NOPB are the only viable options among the listed parts.

Q: What is the output current capability difference between the TSV633IST and substitute parts?

A: The TSV633IST provides 74 mA output current per channel. The AD8592ARMZ-REEL offers the highest output current at 250 mA per channel. The LMV792MM/NOPB provides 60 mA per channel, the LMV712 series provides 50 mA per channel, and the MAX9917 series provides the lowest at 15 mA per channel. Applications requiring output currents exceeding 74 mA must employ the AD8592ARMZ-REEL.

Q: Are all substitute parts RoHS3 compliant?

A: The AD8592ARMZ-REEL, LMV712Q1MM/NOPB, LMV712Q1MMX/NOPB, MAX9917EUB+, and MAX9917EUB+T are all ROHS3 compliant. The LMV792MM/NOPB RoHS status is not specified in the provided data. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute parts are suitable for applications requiring both automotive qualification and full temperature range operation?

A: The LMV712Q1MM/NOPB and LMV712Q1MMX/NOPB are the only substitute parts that provide both AEC-Q100 automotive qualification and full -40°C to 125°C operating temperature range. These parts are direct functional equivalents for automotive applications requiring the complete temperature specification of the TSV633IST.
