TSV855AIPT Equivalent & Substitute Parts

Part Overview

The TSV855AIPT is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring four independent amplifier circuits in a 16-TSSOP surface-mount package. This device is designed for rail-to-rail output operation across automotive-grade applications with AEC-Q100 qualification. The TSV855AIPT is classified as an obsolete product, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical performance specifications and automotive-grade compliance while accommodating package and pinout differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSV855AIPT is determined by the following critical parameters: amplifier type (general purpose), number of circuits (4), output type (rail-to-rail), slew rate (0.7 V/µs), gain bandwidth product (1.3 MHz), input bias current (27 nA), input offset voltage (800 µV), supply current (130 µA across four channels), output current per channel (70 mA), supply voltage range (2.5 V to 5.5 V), operating temperature range (-40°C to 125°C), automotive grade classification, and AEC-Q100 qualification.

The TSV854AIPT qualifies as a direct substitute based on matching all electrical performance specifications. The primary difference is the package configuration: the TSV854AIPT uses a 14-TSSOP package instead of the 16-TSSOP package of the TSV855AIPT. Both devices maintain identical electrical characteristics, automotive-grade compliance, and AEC-Q100 qualification. The TSV854AIPT is currently in active product status, making it suitable for new designs requiring equivalent performance.

Parameter Comparison

Engineering Selection Recommendations

The TSV854AIPT is the primary substitute for the obsolete TSV855AIPT. Both devices are manufactured by STMicroelectronics and maintain identical electrical performance specifications across all critical parameters including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. Both devices carry automotive-grade classification and AEC-Q100 qualification, ensuring compliance with automotive reliability standards.

The TSV854AIPT is currently in active product status, providing long-term availability and supply chain stability compared to the obsolete TSV855AIPT. The primary design consideration is the package difference: the TSV854AIPT uses a 14-TSSOP package versus the 16-TSSOP package of the TSV855AIPT. This package change requires PCB layout modification and pinout verification during design transition. Both packages maintain the same body width (0.173", 4.40mm) and are surface-mount compatible.

For applications where the 16-TSSOP package is mandatory and cannot be modified, the TSV855AIPT remains available in current inventory. However, for new designs and production transitions, the TSV854AIPT is the recommended selection due to its active product status and equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the TSV854AIPT directly replace the TSV855AIPT without circuit modification?

A: The TSV854AIPT provides identical electrical performance and can functionally replace the TSV855AIPT. However, the package difference (14-TSSOP versus 16-TSSOP) requires PCB layout redesign and pinout verification. Direct socket substitution is not possible without PCB modification.

Q: What is the primary difference between the TSV855AIPT and TSV854AIPT?

A: The TSV855AIPT uses a 16-TSSOP package, while the TSV854AIPT uses a 14-TSSOP package. All electrical specifications, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range, are identical between the two devices.

Q: Are both devices automotive-grade qualified?

A: Yes, both the TSV855AIPT and TSV854AIPT carry automotive-grade classification and AEC-Q100 qualification, meeting automotive reliability and quality standards.

Q: Why is the TSV855AIPT listed as obsolete?

A: The TSV855AIPT is classified as an obsolete product by STMicroelectronics. The TSV854AIPT is the active equivalent, providing the same electrical performance in an alternative package configuration.

Q: What are the supply voltage requirements for both devices?

A: Both the TSV855AIPT and TSV854AIPT operate across a supply voltage range of 2.5 V to 5.5 V, supporting single-supply and dual-supply configurations within this range.
