LT1468CDD Equivalent & Substitute Parts

Part Overview

The LT1468CDD is a general-purpose operational amplifier manufactured by Analog Devices Inc., housed in an 8-DFN (3x3) surface mount package with exposed pad. This device is classified as obsolete, indicating it has been discontinued from active production. The LT1468CDD delivers a gain-bandwidth product of 90 MHz with a slew rate of 22 V/µs, making it suitable for general-purpose amplification applications requiring moderate bandwidth and speed characteristics. Due to its obsolete status, identifying equivalent substitute parts with identical electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT1468CDD is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for slew rate, gain-bandwidth product, input bias current, input offset voltage, supply current, output current capability, supply voltage range, operating temperature range, and physical package configuration. The 8-DFN (3x3) surface mount package with exposed pad is a critical mechanical requirement that must be preserved. All substitute candidates must be manufactured by Analog Devices Inc. and derived from the same LT1468 base product number to ensure functional and pin-level compatibility.

The key parameters that determine substitution eligibility are:

• Slew Rate: 22 V/µs
• Gain Bandwidth Product: 90 MHz
• Input Bias Current: 10 nA
• Input Offset Voltage: 100 µV
• Supply Current: 3.9 mA
• Output Current per Channel: 22 mA
• Supply Voltage Range: 9 V to 30 V
• Operating Temperature Range: 0°C to 70°C
• Package: 8-DFN (3x3) with exposed pad

Parameter Comparison

Engineering Selection Recommendations

The LT1468CDD#PBF is the direct equivalent substitute for the obsolete LT1468CDD. Both parts are manufactured by Analog Devices Inc. and share identical electrical and mechanical specifications across all measured parameters. The primary distinction is product status: the LT1468CDD#PBF is actively produced and available, whereas the LT1468CDD is obsolete.

The LT1468CDD#PBF carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for modern manufacturing and supply chain requirements. The packaging designation "#PBF" indicates lead-free plating, which is standard for current production. Both parts are housed in the 8-DFN (3x3) surface mount package with exposed pad and maintain identical moisture sensitivity levels.

For new designs or replacement procurement, the LT1468CDD#PBF is the appropriate selection due to its active production status and regulatory compliance certifications. For legacy system maintenance where the original LT1468CDD is specified, the LT1468CDD#PBF provides complete functional and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LT1468CDD#PBF be used as a direct replacement for the LT1468CDD?

A: Yes. The LT1468CDD#PBF is a direct equivalent substitute. All electrical parameters, including slew rate, gain-bandwidth product, input bias current, input offset voltage, supply current, and output current specifications are identical. The physical package, pin configuration, and operating temperature range are also identical. The primary difference is that the LT1468CDD#PBF is actively produced while the LT1468CDD is obsolete.

Q: Are there any package or pinout differences between these parts?

A: No. Both the LT1468CDD and LT1468CDD#PBF use the 8-DFN (3x3) surface mount package with exposed pad. Pin configuration and mechanical dimensions are identical, allowing direct PCB-level substitution without layout modification.

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

A: The "#PBF" suffix indicates lead-free plating finish, which is the standard for current production parts. This designation reflects compliance with RoHS3 regulations and modern environmental standards.

Q: Are there compliance or regulatory differences between the two parts?

A: The LT1468CDD#PBF carries ROHS3 compliance and REACH unaffected status. The original LT1468CDD, being obsolete, does not have current regulatory certifications listed. For applications requiring regulatory compliance documentation, the LT1468CDD#PBF is the appropriate choice.

Q: Can I use the LT1468CDD#PBF in existing designs that specify the LT1468CDD?

A: Yes. The LT1468CDD#PBF is functionally and mechanically equivalent to the LT1468CDD. No circuit design changes, PCB modifications, or firmware updates are required. The substitution is direct and transparent at the system level.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Are both parts available in the same packaging options?

A: The LT1468CDD#PBF is supplied in tube packaging. Both parts are available in the same 8-DFN (3x3) surface mount package configuration with exposed pad.
