LTC6247CDC Equivalent & Substitute Parts

Part Overview

The LTC6247CDC 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, making it suitable for applications requiring high-speed signal conditioning and amplification across supply voltages from 2.5 V to 5.25 V.

The LTC6247CDC is classified as obsolete. Locating active production alternatives is necessary to ensure long-term design support, supply chain continuity, and access to current manufacturing quality assurance protocols.

Parameter Comparison

Engineering Selection Recommendations

The LTC6247CDC#PBF is the direct active-production equivalent of the LTC6247CDC. Both devices share identical electrical performance specifications and mechanical packaging, enabling direct substitution at the component level.

Product Status Consideration: The LTC6247CDC is classified as obsolete, whereas the LTC6247CDC#PBF maintains active production status. Selection of the active variant ensures access to current manufacturing batches, established supply chain channels, and ongoing quality assurance documentation from Analog Devices Inc.

Compliance and Certification: The LTC6247CDC#PBF carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement in regulated industries and markets. These certifications are not specified for the obsolete variant.

Inventory and Availability: The LTC6247CDC#PBF is available in active inventory (891 pieces), supporting immediate procurement requirements. The obsolete LTC6247CDC remains available in limited quantity (1151 pieces) but should not be selected for new designs or long-term production commitments.

Frequently Asked Questions (FAQ)

Q: Can the LTC6247CDC#PBF replace the LTC6247CDC in existing designs?

A: Yes. The LTC6247CDC#PBF is electrically and mechanically identical to the LTC6247CDC. All electrical parameters, including slew rate, gain-bandwidth product, supply voltage range, and output current capability, are equivalent. The 8-DFN (2x2) package footprint and pin configuration are identical, enabling direct board-level substitution without circuit modification.

Q: What is the primary difference between these two part numbers?

A: The LTC6247CDC is obsolete, while the LTC6247CDC#PBF is in active production. The suffix "#PBF" indicates the active production variant with current manufacturing support. The LTC6247CDC#PBF also carries ROHS3 compliance and REACH unaffected certifications, whereas these designations are not specified for the obsolete variant.

Q: Are there any package or pinout differences?

A: No. Both devices use the 8-WFDFN exposed pad package with 2x2 mm dimensions. Pin configuration, signal assignments, and exposed pad layout are identical. No PCB redesign is required when transitioning from LTC6247CDC to LTC6247CDC#PBF.

Q: What supply voltage range does this amplifier support?

A: The LTC6247CDC and LTC6247CDC#PBF operate across a supply voltage span from 2.5 V to 5.25 V, supporting both single-supply and dual-supply configurations within this range.

Q: What is the maximum output current per channel?

A: Each channel delivers a maximum output current of 100 mA, with total supply current consumption of 1.25 mA across both channels.

Q: Is this device suitable for high-speed applications?

A: Yes. The 180 MHz gain-bandwidth product, 120 MHz -3dB bandwidth, and 90 V/µs slew rate support high-speed signal conditioning, transimpedance amplification, and fast-settling applications within the specified operating temperature range of 0°C to 70°C.

Q: What is the moisture sensitivity level?

A: Both variants carry MSL 1 (Unlimited), indicating unlimited shelf life without moisture-related degradation concerns under standard storage conditions.
