LTC1050CS8 Equivalent & Substitute Parts

Part Overview

The LTC1050CS8 is an active chopper (zero-drift) amplifier manufactured by Analog Devices Inc., designed for precision analog signal conditioning applications requiring minimal input offset voltage. This single-circuit operational amplifier operates across a 4.75 V to 16 V supply range with an input offset voltage of 0.5 µV and input bias current of 10 pA, making it suitable for high-precision measurement and instrumentation circuits.

The LTC1050CS8 maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Finding equivalent and substitute parts is necessary to address supply chain flexibility, extended temperature range requirements, or alternative packaging configurations while maintaining electrical and mechanical compatibility.

LTC1050CS8#PBF as Direct Substitute:

The LTC1050CS8#PBF is a direct functional equivalent to the LTC1050CS8. Both parts share identical electrical specifications across all critical parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and supply voltage range. Both maintain the same 8-SOIC surface mount package configuration and are manufactured by Analog Devices Inc.

The LTC1050CS8#PBF offers an extended operating temperature range of -40°C to 85°C compared to the LTC1050CS8 range of 0°C to 70°C. This extended range provides additional operational flexibility for applications requiring lower temperature performance.

Both parts maintain identical compliance certifications: RoHS3 compliance, unlimited moisture sensitivity rating (MSL 1), REACH unaffected status, EAR99 export classification, and HTSUS code 8542.33.0001.

The primary distinction between these parts is packaging format: the LTC1050CS8 is supplied on reel, while the LTC1050CS8#PBF is supplied in tube format. This difference does not affect electrical or mechanical compatibility and is determined by procurement and assembly requirements.

Both parts maintain Active product status with Analog Devices Inc., ensuring continued availability and technical support.

Frequently Asked Questions (FAQ)

Q: Can LTC1050CS8#PBF replace LTC1050CS8 in existing designs?

A: Yes. The LTC1050CS8#PBF is electrically and mechanically equivalent to the LTC1050CS8. All critical electrical parameters—slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and supply voltage range—are identical. Both use the same 8-SOIC surface mount package. The extended operating temperature range of the LTC1050CS8#PBF (-40°C to 85°C versus 0°C to 70°C) provides additional operational capability without affecting compatibility.

Q: What is the difference between LTC1050CS8 and LTC1050CS8#PBF?

A: The primary difference is packaging format. The LTC1050CS8 is supplied on reel, while the LTC1050CS8#PBF is supplied in tube. Both parts are manufactured by Analog Devices Inc. and share identical electrical specifications and the same 8-SOIC package configuration. The #PBF designation indicates lead-free (Pb-free) construction, consistent with RoHS3 compliance requirements for both parts.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LTC1050CS8 and LTC1050CS8#PBF are RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Both maintain REACH unaffected status and EAR99 export classification.
