TSV732IST Equivalent & Substitute Parts

Part Overview

The TSV732IST is a CMOS dual-channel operational amplifier manufactured by STMicroelectronics, housed in an 8-MiniSO surface mount package. This rail-to-rail amplifier operates across a 1.5V to 5.5V supply range and is designed for low-power applications requiring dual-channel amplification. The device is active and in production, with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be achieved within the specified parameter ranges. Alternative devices may be required due to supply availability, packaging preferences, or application-specific performance requirements.

Substitute Part Grouping Explanation

Substitute parts for the TSV732IST are grouped based on strict electrical and mechanical compatibility criteria. All substitute devices must meet the following requirements:

Mandatory Compatibility Parameters:

Dual-channel configuration (2 circuits)
Rail-to-rail output capability
Surface mount technology
8-pin MSOP or VSSOP package (0.118", 3.00mm width)
Operating temperature range: -40°C to 125°C
Supply voltage span: minimum 1.5V to 1.8V, maximum 5.5V

Electrical Performance Considerations: Substitute devices are organized by amplifier type (CMOS, General Purpose, or Chopper/Zero-Drift). While slew rate, gain bandwidth product, and current specifications may vary, substitutes maintain functional equivalence within the dual-channel, rail-to-rail amplifier category. Input bias current, input offset voltage, and supply current are secondary selection criteria based on application requirements.

Engineering Selection Recommendations

CMOS Amplifier Substitutes (Lowest Power Operation):

The LPV542DGKR and LPV542DGKT devices are CMOS amplifiers from Texas Instruments offering ultra-low supply current (0.48 µA across both channels). These parts are suitable for battery-powered or energy-harvesting applications where power consumption is the primary design constraint. Both variants are ROHS3 compliant with MSL 1 rating. The primary trade-off is significantly reduced slew rate (0.0037 V/µs) and gain bandwidth product (8 kHz) compared to the TSV732IST.

General Purpose Amplifier Substitutes (Balanced Performance):

The MCP6002-E/MS and MCP6002-I/MS devices from Microchip Technology provide general-purpose amplification with slew rate of 0.6 V/µs and 1 MHz gain bandwidth product. These parts maintain 1 pA input bias current matching the TSV732IST and are ROHS3 compliant with MSL 1. The MCP6002-E/MS operates across -40°C to 125°C, while the MCP6002-I/MS operates -40°C to 85°C. Both are available in 8-MSOP packaging.

The ISL28213FUZ and ISL28214FUZ devices from Renesas Electronics offer higher performance with slew rates of 1 V/µs and 2.5 V/µs respectively, and gain bandwidth products of 2 MHz and 5 MHz. These parts carry MSL 2 rating (1-year moisture sensitivity) and are suitable for applications requiring faster signal processing.

Zero-Drift Amplifier Substitutes (Precision Applications):

The ADA4051-2ARMZ and ADA4051-2ARMZ-R7 devices from Analog Devices are chopper-stabilized amplifiers offering extremely low input offset voltage (2 µV) and low input bias current (20 pA). These parts are ROHS3 compliant with MSL 1 rating and are suitable for precision measurement and instrumentation applications. The primary trade-off is reduced slew rate (0.06 V/µs) and gain bandwidth product (125 kHz).

Packaging and Availability Considerations:

All substitute parts maintain 8-pin surface mount packages compatible with the TSV732IST footprint. Packaging variants (Tube, Cut Tape & Digi-Reel, Tape & Reel) do not affect electrical or mechanical compatibility. All listed substitutes are active products with ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the ADA4051-2ARMZ replace the TSV732IST in all applications?

A: The ADA4051-2ARMZ is mechanically compatible and maintains dual-channel, rail-to-rail operation across the required temperature range. However, the significantly lower slew rate (0.06 V/µs versus 0.35 V/µs) and gain bandwidth product (125 kHz versus 900 kHz) restrict its use to applications not requiring fast signal transitions. Substitution is valid only for precision, low-frequency measurement circuits.

Q: What is the difference between LPV542DGKR and LPV542DGKT?

A: Both devices are electrically identical CMOS amplifiers from Texas Instruments. The primary difference is packaging format: LPV542DGKR is supplied in Cut Tape & Digi-Reel format, while LPV542DGKT is supplied in Tape & Reel format. Both are suitable substitutes for the TSV732IST from an electrical and mechanical standpoint.

Q: Are the MCP6002-E/MS and MCP6002-I/MS interchangeable?

A: Both devices are electrically identical general-purpose amplifiers from Microchip Technology with identical electrical specifications. The difference is operating temperature range: MCP6002-E/MS operates -40°C to 125°C, while MCP6002-I/MS operates -40°C to 85°C. Selection depends on the application's maximum operating temperature requirement.

Q: Does the TSV732IST require any special handling compared to substitute parts?

A: The TSV732IST carries MSL 1 (unlimited moisture sensitivity), matching the ADA4051-2ARMZ, LPV542 variants, and MCP6002 devices. The ISL28213FUZ and ISL28214FUZ carry MSL 2 (1-year moisture sensitivity), requiring more stringent moisture control during storage and handling. All parts are ROHS3 compliant and REACH unaffected.

Q: Can I use the ISL28214FUZ in place of the TSV732IST for high-speed applications?

A: The ISL28214FUZ offers higher slew rate (2.5 V/µs) and gain bandwidth product (5 MHz) compared to the TSV732IST (0.35 V/µs, 900 kHz), making it suitable for faster signal processing. However, supply current is significantly higher (300 µA versus 58 µA), which may impact power budget in battery-powered designs. Mechanical compatibility and operating temperature range are maintained.

Q: What is the primary advantage of the LMP7732 series over the TSV732IST?

A: The LMP7732MM/NOPB and LMP7732MME/NOPB devices offer significantly higher gain bandwidth product (22 MHz) and slew rate (2.4 V/µs), suitable for wideband signal conditioning and high-frequency applications. The trade-off is substantially higher supply current (5 mA versus 58 µA) and higher input bias current (14 nA versus 1 pA).

Q: Are all substitute parts available in the same 8-MiniSO package as the TSV732IST?

A: The TSV732IST is supplied in 8-MiniSO package. Substitute parts use equivalent 8-pin surface mount packages: 8-MSOP (Microchip, Renesas, Analog Devices) and 8-VSSOP (Texas Instruments). These packages are mechanically and electrically compatible with the same PCB footprint and pin assignments.

Q: Which substitute part offers the lowest power consumption?

A: The LPV542DGKR and LPV542DGKT devices offer the lowest supply current at 0.48 µA across both channels, compared to 58 µA for the TSV732IST. These CMOS amplifiers are optimized for ultra-low-power applications but operate at significantly reduced bandwidth (8 kHz) and slew rate (0.0037 V/µs).
