LT6018IDE Equivalent & Substitute Parts

Part Overview

The LT6018IDE is a general-purpose operational amplifier manufactured by Analog Devices Inc., housed in a 12-DFN (4x3) surface mount package. This device is classified as obsolete and is no longer in active production. The LT6018IDE serves applications requiring low-distortion amplification with moderate bandwidth and low input offset voltage characteristics. Due to its obsolete status, identification of equivalent substitute parts is necessary for design continuity, component sourcing, and system maintenance.

Substitute Part Grouping Explanation

Substitution of the LT6018IDE is determined by electrical and mechanical parameter compatibility. The primary substitution criteria are:

Electrical Parameters:

• Slew Rate: 30 V/µs (must match)
• Gain Bandwidth Product: 15 MHz (must match)
• Voltage - Input Offset: 8 µV (must match)
• Current - Supply: 7.2 mA (must match)
• Current - Output / Channel: 100 mA (must match)
• Voltage - Supply Span: 8 V to 33 V (must match)
• Operating Temperature Range: -40°C to 85°C (must match)

Mechanical Parameters:

• Amplifier Type: General Purpose (must match)
• Number of Circuits: 1 (must match)
• Mounting Type: Surface Mount (must match)
• Package / Case: 10-WFQFN Exposed Pad (must match)
• Supplier Device Package: 12-DFN (4x3) (must match)

The LT6018IDE#PBF is identified as a direct substitute based on full alignment of all electrical and mechanical parameters specified above.

Parameter Comparison

Engineering Selection Recommendations

The LT6018IDE#PBF serves as a functional equivalent to the LT6018IDE based on matching electrical performance and mechanical package specifications. Both devices are classified as obsolete products and share identical core operational parameters including slew rate, gain bandwidth product, supply current, output current capability, and operating temperature range.

The LT6018IDE#PBF exhibits a lower input bias current specification (60 nA versus 150 nA), which represents an improvement in input stage performance and does not preclude substitution in applications designed for the original LT6018IDE.

A material difference exists in regulatory compliance status: the LT6018IDE#PBF is designated as RoHS non-compliant, whereas the LT6018IDE compliance status is not specified in the provided data. Applications subject to RoHS requirements must account for this distinction during component selection.

Both devices are manufactured by entities within the Linear Technology / Analog Devices corporate structure, ensuring design continuity and functional compatibility at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can the LT6018IDE#PBF be used as a direct replacement for the LT6018IDE in existing designs?

A: The LT6018IDE#PBF is electrically and mechanically compatible with the LT6018IDE for applications where the lower input bias current (60 nA) is acceptable. Both devices operate within identical supply voltage ranges (8 V to 33 V), deliver equivalent slew rate and bandwidth performance, and are housed in the same 12-DFN (4x3) package. Compliance requirements must be evaluated independently.

Q: What is the significance of the different input bias current specifications?

A: The LT6018IDE#PBF specifies 60 nA input bias current compared to 150 nA for the LT6018IDE. This represents superior input stage performance in the substitute part. Applications designed for the original 150 nA specification will operate within acceptable parameters with the lower bias current of the substitute.

Q: Are there package compatibility concerns between these parts?

A: Both the LT6018IDE and LT6018IDE#PBF utilize identical packaging: 10-WFQFN Exposed Pad with 12-DFN (4x3) physical dimensions. No PCB layout modifications are required for substitution.

Q: What is the impact of the RoHS non-compliance designation on the LT6018IDE#PBF?

A: The LT6018IDE#PBF is designated RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must account for this regulatory difference. The LT6018IDE compliance status is not specified in available data.

Q: Are both parts still available for procurement?

A: Both the LT6018IDE and LT6018IDE#PBF are classified as obsolete products. Inventory availability is limited to existing stock. The LT6018IDE#PBF currently shows higher inventory levels (1570 pieces) compared to the LT6018IDE (817 pieces).

Q: What is the base product number for these devices?

A: The base product number for both the LT6018IDE and LT6018IDE#PBF is LT6018. This designation identifies the core device family and electrical specifications.
