LTC1050HS8 Equivalent & Substitute Parts

Part Overview

The LTC1050HS8 is an active chopper (zero-drift) amplifier manufactured by Analog Devices Inc., designed for precision analog signal conditioning applications requiring extremely low input offset voltage and minimal drift characteristics. This single-circuit operational amplifier is classified as a linear amplifier and is currently in active production status. The device is housed in an 8-SOIC surface mount package with a width of 0.154 inches (3.90mm).

Identifying equivalent and substitute parts for the LTC1050HS8 becomes necessary when managing inventory constraints, addressing supply chain disruptions, or consolidating component procurement across manufacturing facilities. Substitute parts must maintain electrical performance specifications and physical compatibility to ensure seamless integration into existing circuit designs without redesign requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTC1050HS8 is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier type classification (Chopper/Zero-Drift technology)
• Number of circuits (single circuit configuration)
• Slew rate (4 V/µs)
• Gain bandwidth product (2.5 MHz)
• Input bias current (10 pA)
• Input offset voltage (0.5 µV)
• Supply current (1 mA)
• Supply voltage range (4.75 V to 16 V)
• Operating temperature range (-40°C to 125°C)

Physical and Compliance Criteria:

• Mounting type (Surface Mount)
• Package specification (8-SOIC with 0.154" / 3.90mm width)
• RoHS3 compliance status
• Moisture sensitivity level (MSL 1)
• REACH compliance status

Parts meeting all specified parameters within these categories are classified as direct substitutes. Packaging format variations (such as tube versus reel) do not affect electrical or mechanical compatibility and do not preclude substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The LTC1050HS8#PBF is a direct functional and physical equivalent to the LTC1050HS8. Both parts are manufactured by Analog Devices Inc. and maintain identical electrical specifications across all measured parameters, including precision performance metrics such as input offset voltage (0.5 µV) and input bias current (10 pA).

Both parts carry active product status, indicating ongoing manufacturer support and availability. Compliance certifications are identical: ROHS3 compliance, REACH unaffected status, and MSL 1 rating ensure compatibility with current manufacturing and environmental standards.

The primary distinction between these parts is packaging format. The LTC1050HS8 is supplied in standard reel packaging, while the LTC1050HS8#PBF is supplied in tube packaging. This packaging difference does not affect electrical performance, mechanical fit, or circuit functionality. Selection between these variants depends solely on procurement and assembly process requirements.

Both parts are suitable for direct substitution in applications requiring precision zero-drift amplification with supply voltage ranges from 4.75 V to 16 V and operating temperatures from -40°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the LTC1050HS8#PBF be used as a direct replacement for the LTC1050HS8?

A: Yes. The LTC1050HS8#PBF is a direct substitute for the LTC1050HS8. All electrical parameters, physical dimensions, and compliance certifications are identical. The only difference is packaging format (tube versus reel).

Q: What is the significance of the "#PBF" designation in the LTC1050HS8#PBF part number?

A: The "#PBF" suffix indicates lead-free (Pb-free) packaging and RoHS compliance. Both the LTC1050HS8 and LTC1050HS8#PBF are RoHS3 compliant and lead-free.

Q: Are there any differences in electrical performance between these two parts?

A: No. Both parts deliver identical electrical performance: 4 V/µs slew rate, 2.5 MHz gain bandwidth product, 0.5 µV input offset voltage, 10 pA input bias current, and 1 mA supply current across the 4.75 V to 16 V supply range.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. Both parts use the 8-SOIC surface mount package with identical pinout and physical dimensions (0.154" / 3.90mm width). No PCB redesign or rework is required when substituting between these parts.

Q: What is the operating temperature range for both parts?

A: Both the LTC1050HS8 and LTC1050HS8#PBF operate across the temperature range of -40°C to 125°C.

Q: Are both parts currently available from the manufacturer?

A: Yes. Both parts maintain active product status with Analog Devices Inc., indicating ongoing production and availability.

Q: What supply voltage range is supported by these amplifiers?

A: Both parts support a supply voltage range from 4.75 V (minimum) to 16 V (maximum).

Q: How do these zero-drift amplifiers differ from standard operational amplifiers?

A: Zero-drift (chopper) amplifiers use internal switching techniques to eliminate offset voltage drift over temperature and time. The LTC1050HS8 and LTC1050HS8#PBF achieve 0.5 µV input offset voltage with minimal drift characteristics, making them suitable for precision measurement and signal conditioning applications where standard op-amps would introduce unacceptable errors.
