AMP02FS Equivalent & Substitute Parts

Part Overview

The AMP02FS is a single-circuit instrumentation amplifier manufactured by Analog Devices Inc., housed in a 16-SOIC surface mount package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and production continuity. The AMP02FS operates across a supply voltage range of 9V to 36V with an operating temperature range of -40°C to 85°C, making it suitable for industrial and precision measurement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMP02FS is determined by functional equivalence within the instrumentation amplifier category, maintaining compatibility across the following critical parameters: single-circuit configuration, 16-SOIC package footprint, surface mount mounting type, and operating temperature range of -40°C to 85°C. Substitute parts must accommodate the supply voltage requirements and maintain electrical performance within acceptable tolerances for the application.

The AMP02FSZ represents a direct manufacturer equivalent from Analog Devices Inc., differing only in packaging format (tube versus unspecified) and product status (active versus obsolete). The INA111 series devices from Texas Instruments (INA111AU, INA111AU/1K, and INA111BU) function as similar instrumentation amplifiers with enhanced electrical performance characteristics while maintaining package compatibility and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

AMP02FSZ is the primary direct substitute for the AMP02FS. Both devices are manufactured by Analog Devices Inc. and share identical electrical specifications, package configuration, and operating parameters. The AMP02FSZ holds active product status and is ROHS3 compliant with REACH unaffected designation, providing regulatory compliance advantages over the obsolete AMP02FS. This substitution requires no circuit redesign or performance trade-offs.

INA111 Series Devices (INA111AU, INA111AU/1K, INA111BU) from Texas Instruments function as alternative instrumentation amplifiers with enhanced performance characteristics. These devices exhibit superior slew rate (17 V/µs versus 6 V/µs), increased bandwidth (2 MHz versus 1.2 MHz), and significantly lower input bias current (2 pA versus 4 nA). All INA111 variants maintain the 16-SOIC package footprint and -40°C to 85°C operating temperature range. The minimum supply voltage requirement increases from 9V to 12V, which must be verified against circuit design specifications. All INA111 devices are active products with ROHS3 compliance and REACH unaffected status.

INA111BU provides the lowest input offset voltage (100 µV) among the INA111 variants, offering enhanced precision for applications requiring tighter offset specifications compared to the AMP02FS (40 µV) and INA111AU variants (200 µV).

Frequently Asked Questions (FAQ)

Q: Can the AMP02FSZ be used as a direct replacement for the AMP02FS without circuit modifications?

A: Yes. The AMP02FSZ is electrically and mechanically identical to the AMP02FS. Both devices share the same electrical specifications, 16-SOIC package footprint, and operating parameters. The substitution requires no circuit redesign.

Q: What are the key differences between the AMP02FS and INA111 series devices?

A: The INA111 series offers enhanced performance with higher slew rate (17 V/µs versus 6 V/µs), increased bandwidth (2 MHz versus 1.2 MHz), and lower input bias current (2 pA versus 4 nA). The minimum supply voltage requirement increases from 9V to 12V. All devices maintain the same 16-SOIC package and operating temperature range.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts (AMP02FSZ, INA111AU, INA111AU/1K, and INA111BU) use the 16-SOIC package with 0.295" width and 7.50mm dimensions, ensuring PCB footprint compatibility with the AMP02FS.

Q: What is the significance of the INA111AU/1K designation?

A: The INA111AU/1K is functionally equivalent to the INA111AU, with identical electrical specifications and performance characteristics. The designation reflects packaging or distribution configuration differences.

Q: Do the substitute parts meet current regulatory compliance standards?

A: Yes. All active substitute parts (AMP02FSZ, INA111AU, INA111AU/1K, and INA111BU) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The obsolete AMP02FS does not specify compliance status.

Q: Which substitute part should be selected for applications requiring the lowest input offset voltage?

A: The INA111BU provides the lowest input offset voltage at 100 µV among the available substitutes, compared to 40 µV for the AMP02FS and 200 µV for the INA111AU variants.

Q: What is the impact of the increased minimum supply voltage requirement in INA111 devices?

A: INA111 series devices require a minimum supply voltage of 12V, compared to 9V for the AMP02FS. Circuit designs operating at supply voltages between 9V and 12V must retain the AMP02FSZ or verify that the application can accommodate the higher minimum voltage requirement.

Q: Are there packaging format differences among the substitute parts?

A: Yes. The AMP02FSZ is supplied in tube packaging, INA111AU in tube packaging, INA111AU/1K in unspecified packaging, and INA111BU in bulk packaging. All devices maintain the same 16-SOIC component package format suitable for surface mount assembly.
