Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1807IS8 is determined by strict equivalence across all electrical performance parameters and mechanical specifications. The primary substitution criterion is the matching of the base product number LT1807 combined with identical electrical characteristics: dual general-purpose amplifier circuits, rail-to-rail output configuration, 140 V/µs slew rate, 325 MHz gain-bandwidth product, and 8-SOIC surface-mount packaging.

The key parameters that govern substitution eligibility are:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Slew Rate: 140 V/µs
• Gain Bandwidth Product: 325 MHz
• Current - Input Bias: 1 µA
• Voltage - Input Offset: 100 µV
• Current - Supply: 9 mA (x2 Channels)
• Current - Output / Channel: 85 mA
• Voltage - Supply Span: 2.5 V to 12.6 V
• Operating Temperature: -40°C to 85°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Substitutes are identified based on identical electrical performance and package specifications. Packaging format variations (such as tube versus alternative packaging) do not affect electrical substitutability when all performance parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The LT1807IS8 and LT1807IS8#PBF are direct electrical and mechanical equivalents. Both devices are manufactured by Analog Devices Inc., maintain active product status, and comply with ROHS3 and REACH regulatory requirements. The distinction between these parts is limited to packaging format: the LT1807IS8 is supplied in standard packaging, while the LT1807IS8#PBF is supplied in tube packaging.

Selection between these equivalent parts should be based on procurement requirements and supply chain availability. Both parts satisfy identical electrical performance specifications and are suitable for direct substitution in applications requiring dual general-purpose operational amplifiers with rail-to-rail output capability, 325 MHz gain-bandwidth product, and operation across the -40°C to 85°C temperature range.

The MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions for either part, simplifying storage and handling requirements. Both parts are suitable for surface-mount assembly in 8-SOIC package configurations.

Frequently Asked Questions (FAQ)

Q: Can the LT1807IS8#PBF be used as a direct replacement for the LT1807IS8?

A: Yes. The LT1807IS8#PBF is a direct electrical and mechanical equivalent. All performance parameters, including slew rate, gain-bandwidth product, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature specifications 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 that the part is supplied in tube packaging format. This designation does not affect electrical performance or functional compatibility. The part number LT1807IS8#PBF represents the same die and electrical specifications as LT1807IS8, with a different packaging and delivery method.

Q: Are there any thermal or performance differences between LT1807IS8 and LT1807IS8#PBF?

A: No. Both parts are manufactured using identical processes and specifications. Thermal characteristics, electrical performance, and reliability are equivalent. The 8-SOIC package dimensions (0.154" width, 3.90mm) are identical for both variants.

Q: What is the significance of the MSL rating of 1 for these parts?

A: An MSL rating of 1 (Unlimited) indicates that these components have no moisture sensitivity restrictions. They can be stored and handled without special moisture control measures, simplifying inventory management and reducing handling costs compared to higher MSL-rated components.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both the LT1807IS8 and LT1807IS8#PBF use identical 8-SOIC surface-mount package specifications and can be placed using the same PCB footprint and assembly parameters. No design or layout modifications are required when substituting between these parts.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. These regulatory certifications ensure compliance with environmental and hazardous substance restrictions applicable to electronic components in regulated markets.

Q: Are both parts actively manufactured and supported?

A: Yes. Both the LT1807IS8 and LT1807IS8#PBF maintain active product status with Analog Devices Inc., ensuring continued availability, technical support, and compliance with current manufacturing standards.
