LMC6044-MDC Equivalent & Substitute Parts

Part Overview

The LMC6044-MDC is a CMOS amplifier integrated circuit featuring four independent operational amplifier circuits with push-pull, rail-to-rail output configuration. This die-format component is designed for applications requiring low input bias current and low input offset voltage in a compact form factor. The LMC6044-MDC carries a Last Time Buy product status, indicating that this specific packaging variant is no longer in active production. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for new production runs and design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMC6044-MDC is determined by electrical and functional equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: CMOS topology
• Number of Circuits: 4 independent amplifier channels
• Output Type: Push-Pull, Rail-to-Rail configuration
• Slew Rate: 0.02 V/µs
• Gain Bandwidth Product: 100 kHz
• Input Bias Current: 0.002 pA
• Input Offset Voltage: 1 mV
• Supply Current: 52 µA (x4 Channels)
• Output Current per Channel: 40 mA
• Supply Voltage Range: 4.5 V to 15.5 V
• Operating Temperature Range: -40°C to 85°C

Functional Equivalence Criteria:

• Base Product Number: LMC6044 (same die design)
• Compliance: ROHS3 Compliant, REACH Unaffected
• Moisture Sensitivity: MSL 1 (Unlimited)

The primary difference between the main part and substitute parts lies in packaging and mounting configuration. The LMC6044-MDC is supplied as a bare die, while substitute parts are packaged in industry-standard surface-mount formats. All electrical and functional parameters remain identical across the product family.

Engineering Selection Recommendations

The LMC6044IMX/NOPB represents the direct functional equivalent to the LMC6044-MDC with identical electrical specifications and performance characteristics. Selection between these parts is determined by application requirements and manufacturing process constraints.

LMC6044-MDC Selection Criteria:

• Applications requiring bare die integration for hybrid circuit assembly
• Custom packaging or encapsulation processes
• Existing inventory depletion (Last Time Buy status)

LMC6044IMX/NOPB Selection Criteria:

• Standard surface-mount assembly processes
• Active product status ensures long-term availability
• Conventional PCB integration workflows
• Tape & Reel packaging for automated pick-and-place assembly

Both parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited). The LMC6044IMX/NOPB is the recommended selection for new designs due to its Active product status, which guarantees continued manufacturing support and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Are the LMC6044-MDC and LMC6044IMX/NOPB electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range. The LMC6044 base product number confirms they are derived from the same die design.

Q: What is the primary difference between these two parts?

A: The primary difference is packaging format. The LMC6044-MDC is supplied as a bare die for hybrid circuit applications, while the LMC6044IMX/NOPB is packaged in a 14-SOIC surface-mount package for standard PCB assembly.

Q: Why is the LMC6044-MDC marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific die-format variant. Existing inventory is available for purchase, but no future production runs are planned. The LMC6044IMX/NOPB remains in active production.

Q: Can I use the LMC6044IMX/NOPB as a direct replacement in a design originally specified for the LMC6044-MDC?

A: Direct replacement depends on the application's physical and assembly requirements. If the design uses hybrid circuit assembly with bare die integration, the LMC6044IMX/NOPB cannot be used without redesigning the assembly process. If the design can accommodate standard surface-mount components, the LMC6044IMX/NOPB is a suitable substitute.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited), and ECCN EAR99 classification.

Q: What is the supply voltage range for both parts?

A: Both the LMC6044-MDC and LMC6044IMX/NOPB operate across a supply voltage range of 4.5 V to 15.5 V, enabling use in single-supply and dual-supply configurations.

Q: How many amplifier circuits are integrated in each part?

A: Both parts contain four independent CMOS operational amplifier circuits with push-pull, rail-to-rail output configuration.
