TS952IYD Equivalent & Substitute Parts

Part Overview

The TS952IYD is a general-purpose operational amplifier manufactured by STMicroelectronics, featuring dual circuits in an 8-SOIC surface-mount package. This device is classified as obsolete, necessitating identification of active equivalent components for new designs and production continuity. The TS952IYD operates across a wide supply voltage range (2.7V to 12V) with rail-to-rail output capability, making it suitable for automotive-grade applications requiring AEC-Q100 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS952IYD is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-SOIC surface-mount package with identical 0.154" (3.90mm) width to ensure PCB footprint compatibility without layout modifications.

Functional Architecture: The substitute must provide dual general-purpose operational amplifier circuits with rail-to-rail output capability to maintain circuit functionality.

Supply Voltage Range: The substitute must operate within the minimum supply voltage of 2.7V and maximum supply voltage of 12V. Substitutes with narrower supply ranges may not be compatible with all applications using the TS952IYD.

Operating Temperature Range: The substitute must support the full -40°C to 125°C operating temperature range to ensure reliability across automotive and industrial environments.

Compliance Standards: RoHS3 compliance and MSL Level 1 rating are required to meet environmental and handling requirements equivalent to the original part.

Parameter Comparison

Engineering Selection Recommendations

The AD8542ARZ from Analog Devices Inc. is an active substitute for the obsolete TS952IYD. Both devices share identical package geometry (8-SOIC), mounting type (surface mount), operating temperature range (-40°C to 125°C), and compliance certifications (ROHS3, MSL Level 1).

The AD8542ARZ maintains functional equivalence as a dual general-purpose rail-to-rail operational amplifier. However, the maximum supply voltage specification differs: the TS952IYD supports up to 12V, while the AD8542ARZ is rated to 5.5V maximum. Applications requiring supply voltages above 5.5V cannot use the AD8542ARZ as a direct substitute.

The AD8542ARZ exhibits superior electrical characteristics in several parameters: lower input bias current (4 pA versus 35 nA), lower input offset voltage (1 mV versus 6 mV), and significantly lower supply current (45µA versus 950µA). These improvements result in reduced power consumption and improved precision. The AD8542ARZ provides higher output current capability (30 mA versus 10 mA per channel).

The TS952IYD offers higher gain bandwidth product (3 MHz versus 1 MHz) and faster slew rate (1 V/µs versus 0.92 V/µs), which may be required for specific high-frequency applications.

Selection between these devices depends on supply voltage requirements and performance specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can the AD8542ARZ replace the TS952IYD in all applications?

A: The AD8542ARZ is functionally equivalent in package, pin configuration, and operating temperature range. However, applications requiring supply voltages above 5.5V cannot use the AD8542ARZ, as the TS952IYD supports up to 12V. Verify supply voltage requirements before substitution.

Q: Are the pin configurations identical between TS952IYD and AD8542ARZ?

A: Both devices use the 8-SOIC package with identical physical dimensions (0.154" width, 3.90mm). Pin configuration compatibility is assured for dual general-purpose operational amplifier circuits in this package type.

Q: What are the key electrical differences between these parts?

A: The AD8542ARZ provides lower input bias current, lower input offset voltage, and significantly lower supply current consumption. The TS952IYD offers higher gain bandwidth product and faster slew rate. The AD8542ARZ provides higher output current per channel. Selection depends on application-specific performance requirements.

Q: Are both parts RoHS compliant?

A: Yes, both the TS952IYD and AD8542ARZ are ROHS3 compliant with MSL Level 1 moisture sensitivity rating, meeting equivalent environmental and handling standards.

Q: What is the supply voltage limitation for the AD8542ARZ?

A: The AD8542ARZ maximum supply voltage is 5.5V, compared to 12V for the TS952IYD. Applications designed for the full 2.7V to 12V range of the TS952IYD must be re-evaluated if using the AD8542ARZ, particularly those requiring supply voltages above 5.5V.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, both parts use identical 8-SOIC surface-mount package geometry and can occupy the same PCB footprint without layout modifications. Electrical performance differences must be evaluated for the specific circuit application.
