TSV850ILT Equivalent & Substitute Parts

Part Overview

The TSV850ILT is a general-purpose operational amplifier manufactured by STMicroelectronics, housed in a SOT-23-6 surface mount package. This rail-to-rail output amplifier operates across a 2.5V to 5.5V supply range and is designed for low-power analog signal processing applications. The device is actively produced and RoHS3 compliant. Substitute parts are identified when equivalent functional performance, package compatibility, and electrical specifications align with application requirements, enabling design flexibility and supply chain alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSV850ILT are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: SOT-23-6
• Mounting Type: Surface Mount
• Voltage - Supply Span: 2.5V to 5.5V
• Operating Temperature Range: -40°C to 125°C
• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core requirements. Variations in secondary electrical parameters such as slew rate, gain bandwidth product, input bias current, and output current capacity do not disqualify substitution but indicate performance differences that must be evaluated within specific circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TSV850ILT, LMV341IDBVR, and MAX4481AUT+T—are active products with RoHS3 compliance and identical moisture sensitivity ratings. Selection between these devices depends on application-specific electrical performance requirements:

TSV850ILT (STMicroelectronics): Baseline general-purpose amplifier with moderate slew rate (0.7V/µs) and gain bandwidth product (1.3 MHz). Suitable for standard signal conditioning and buffering applications within the specified supply range.

LMV341IDBVR (Texas Instruments): Offers improved slew rate (1V/µs) and lower input bias current (1 pA) compared to TSV850ILT, with higher output current capability (113 mA). Appropriate for applications requiring faster transient response and reduced input offset drift.

MAX4481AUT+T (Analog Devices Inc./Maxim Integrated): Provides lowest supply current consumption (50µA) and lowest input offset voltage (1 mV), with reduced output current capacity (17 mA). Optimized for ultra-low-power applications where supply current minimization is critical.

All parts share identical package footprints (SOT-23-6), supply voltage ranges (2.5V to 5.5V), and operating temperature specifications (-40°C to 125°C), enabling direct substitution at the PCB level. Compliance certifications (RoHS3, REACH Unaffected, EAR99) are equivalent across all three devices.

Frequently Asked Questions (FAQ)

Q: Can the LMV341IDBVR directly replace the TSV850ILT on a PCB?

A: Yes. Both devices use identical SOT-23-6 packaging and pinout configuration. No PCB layout modifications are required. Electrical performance differences (slew rate, input bias current, output current) must be evaluated within the specific circuit application to confirm functional compatibility.

Q: What is the primary difference between the MAX4481AUT+T and the TSV850ILT?

A: The MAX4481AUT+T is optimized for ultra-low-power operation with 50µA supply current versus 130µA for the TSV850ILT. However, the MAX4481AUT+T has significantly lower gain bandwidth product (140 kHz) and output current (17 mA), making it unsuitable for high-speed or high-current-drive applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. TSV850ILT, LMV341IDBVR, and MAX4481AUT+T are all RoHS3 compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part has the lowest input offset voltage?

A: The MAX4481AUT+T has the lowest input offset voltage at 1 mV, compared to 4 mV for TSV850ILT and 0.25 mV for LMV341IDBVR. The LMV341IDBVR offers the best offset voltage performance.

Q: Can these parts operate at supply voltages below 2.5V?

A: No. All three devices require a minimum supply voltage of 2.5V. Operation below this threshold is not specified and may result in unpredictable behavior.

Q: What is the packaging difference between the TSV850ILT and LMV341IDBVR?

A: Both use SOT-23-6 packages. The TSV850ILT is supplied in Tape & Reel (TR) format, while the LMV341IDBVR is available in Cut Tape (CT) & Digi-Reel® format. The physical package and pinout are identical; packaging format affects only procurement and handling logistics.

Q: Which substitute part has the highest output current capability?

A: The LMV341IDBVR provides the highest output current per channel at 113 mA, compared to 70 mA for TSV850ILT and 17 mA for MAX4481AUT+T.

Q: Are all parts suitable for the full -40°C to 125°C temperature range?

A: Yes. All three devices are rated for continuous operation across the -40°C to 125°C temperature range with no derating required within this specification.
