LTC6247IDC Equivalent & Substitute Parts

Part Overview

The LTC6247IDC is a general-purpose operational amplifier featuring dual circuits in a compact 8-DFN (2x2) surface-mount package. This device delivers rail-to-rail output capability with a 180 MHz gain-bandwidth product and 90 V/µs slew rate, suitable for applications requiring high-speed signal conditioning and amplification across supply voltages from 2.5 V to 5.25 V.

The LTC6247IDC is classified as obsolete. Locating equivalent or substitute components is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for systems utilizing this amplifier topology.

Substitute Part Grouping Explanation

Substitution of the LTC6247IDC is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for amplifier topology, circuit count, output configuration, frequency response, slew rate, input characteristics, supply current, output drive capability, supply voltage range, operating temperature, and physical packaging.

The LTC6247IDC#PBF qualifies as a direct substitute based on the following criteria:

• Identical amplifier type and dual-circuit configuration
• Matching rail-to-rail output topology
• Equivalent gain-bandwidth product (180 MHz) and -3dB bandwidth (120 MHz)
• Identical slew rate (90 V/µs)
• Matching input bias current (400 nA) and input offset voltage (100 µV)
• Identical supply current per channel (1.25 mA) and output current capability (100 mA)
• Matching supply voltage range (2.5 V to 5.25 V)
• Identical operating temperature range (-40°C to 85°C)
• Identical package specification (8-WFDFN Exposed Pad, 8-DFN 2x2)
• Identical moisture sensitivity level (MSL 1)

Engineering Selection Recommendations

The LTC6247IDC#PBF is the direct equivalent substitute for the obsolete LTC6247IDC. Both parts are manufactured by Analog Devices Inc. and share identical electrical and mechanical specifications across all parameters.

The primary distinction between these parts is product status and regulatory compliance:

• LTC6247IDC: Obsolete status; limited availability
• LTC6247IDC#PBF: Active product status; full manufacturing support; RoHS3 compliant; REACH unaffected; EAR99 export classification

The LTC6247IDC#PBF is the recommended selection for new designs and ongoing production requirements. This part maintains complete functional and physical compatibility with the original LTC6247IDC while providing access to current manufacturing, quality assurance, and regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Are the LTC6247IDC and LTC6247IDC#PBF electrically identical?

A: Yes. Both parts deliver identical electrical performance across all specified parameters, including gain-bandwidth product, slew rate, input bias current, supply voltage range, and output drive capability.

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

A: The "#PBF" suffix designates a lead-free, RoHS3-compliant version of the component. This marking indicates compliance with environmental and hazardous substance restrictions.

Q: Can the LTC6247IDC#PBF be used as a direct replacement in existing designs?

A: Yes. The LTC6247IDC#PBF is a direct pin-for-pin and functionally equivalent replacement. No circuit modifications or design changes are required.

Q: Are there any package differences between these parts?

A: No. Both parts use the identical 8-WFDFN Exposed Pad package with 2x2 mm dimensions and surface-mount configuration.

Q: Why is the original LTC6247IDC classified as obsolete?

A: Analog Devices Inc. has transitioned production to the RoHS3-compliant LTC6247IDC#PBF variant. The obsolete designation reflects the manufacturer's discontinuation of the non-compliant version.

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

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there supply chain differences between these parts?

A: The LTC6247IDC#PBF is the active production part with full manufacturing support and availability. The LTC6247IDC is obsolete with limited remaining inventory.
