LT1114IS Equivalent & Substitute Parts

Part Overview

The LT1114IS is a general-purpose operational amplifier manufactured by Analog Devices Inc., featuring four independent amplifier circuits in a 16-SOIC surface mount package. This device is classified as an active linear amplifier and maintains Active product status within the manufacturer's portfolio. The LT1114IS serves applications requiring low-power, general-purpose amplification across industrial, consumer, and instrumentation domains. Identifying equivalent and substitute parts becomes necessary when addressing supply chain constraints, packaging preferences, or specific procurement requirements while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LT1114IS are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is grounded in the following deterministic criteria:

Electrical Parameter Equivalence:

• Amplifier type classification (General Purpose)
• Number of independent circuits (4)
• Slew rate performance (0.3 V/µs)
• Gain bandwidth product (750 kHz)
• Input bias current specification (70 pA)
• Input offset voltage specification (20 µV)
• Supply current consumption (350 µA across 4 channels)
• Supply voltage operating range (2 V to 40 V)
• Operating temperature range (-40°C to 85°C)

Mechanical Parameter Equivalence:

• Mounting technology (Surface Mount)
• Package type and dimensions (16-SOIC, 0.154" width, 3.90mm)
• Supplier device package designation (16-SO)

Compliance and Regulatory Equivalence:

• RoHS3 compliance status
• Moisture sensitivity level (MSL 1)
• REACH regulatory status

Parts meeting all these criteria are classified as direct substitutes. Variations in packaging format (such as tube versus alternative delivery methods) do not affect electrical or mechanical compatibility and are considered equivalent for component selection purposes.

Parameter Comparison

Engineering Selection Recommendations

Both the LT1114IS and LT1114IS#PBF are Active products from Analog Devices Inc. and maintain full compliance with ROHS3 and REACH regulatory requirements. The primary distinction between these parts is packaging format: LT1114IS is supplied in standard packaging, while LT1114IS#PBF is supplied in tube packaging. This packaging difference does not affect electrical performance, mechanical compatibility, or regulatory compliance.

Selection between these equivalent parts should be based on procurement requirements and inventory availability. Both parts are suitable for direct substitution in applications requiring general-purpose amplification with four independent circuits, low input bias current, and operation across the -40°C to 85°C temperature range. The identical electrical specifications, package dimensions, and compliance certifications ensure seamless integration into existing designs and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can LT1114IS#PBF be used as a direct replacement for LT1114IS?

A: Yes. The LT1114IS#PBF is a direct substitute for LT1114IS. All electrical parameters, mechanical dimensions, operating temperature range, and regulatory compliance certifications are identical. The only difference is the packaging format (tube versus standard packaging).

Q: What does the "#PBF" designation indicate?

A: The "#PBF" suffix indicates the part is supplied in tube packaging format. This is a packaging and delivery specification only and does not alter the component's electrical characteristics or performance.

Q: Are the pin configurations identical between LT1114IS and LT1114IS#PBF?

A: Yes. Both parts use the 16-SOIC package with identical pin assignments, spacing, and mechanical dimensions (0.154" width, 3.90mm). PCB layouts and footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both LT1114IS and LT1114IS#PBF are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical.

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

A: Both parts operate across -40°C to 85°C. Temperature performance and thermal specifications are identical.

Q: Can these parts be used interchangeably in production?

A: Yes. From an engineering perspective, LT1114IS and LT1114IS#PBF are fully interchangeable. Selection between them is determined by procurement preferences, inventory status, and packaging requirements rather than technical performance differences.

Q: What are the key electrical specifications that define these parts?

A: The defining electrical specifications are: four independent general-purpose amplifier circuits, 750 kHz gain bandwidth product, 0.3 V/µs slew rate, 70 pA input bias current, 20 µV input offset voltage, and operation across 2 V to 40 V supply range.
