Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMC6482AIMX is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Amplifier Type: CMOS
• Number of Circuits: 2 channels
• Output Type: Rail-to-Rail
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Allowable Parameter Variance: Substitute parts must maintain electrical performance within the operational envelope defined by the main part specifications. Variations in slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage span are acceptable provided the substitute part meets or exceeds the performance requirements of the application circuit.

The LMC6482AIMX has two identified substitutes: LMC6482AIMX/NOPB (direct manufacturer equivalent) and TS912BIDT (manufacturer-recommended alternative from STMicroelectronics).

Parameter Comparison

Engineering Selection Recommendations

LMC6482AIMX/NOPB (Texas Instruments)

This part is a direct manufacturer equivalent of the LMC6482AIMX, differing only in packaging designation (Cut Tape & Digi-Reel format). Electrical specifications are identical. Product status is Active, ensuring long-term availability. This substitute is appropriate for all applications currently using the LMC6482AIMX. Inventory availability is higher (65,200 units) compared to the main part number.

TS912BIDT (STMicroelectronics)

This part is a manufacturer-recommended alternative that maintains core functional equivalence in 8-SOIC package format with dual CMOS rail-to-rail amplifier architecture. The TS912BIDT exhibits the following differences:

• Gain Bandwidth Product: 1.4 MHz (versus 1.5 MHz)
• Input Bias Current: 1 pA (versus 0.02 pA)
• Input Offset Voltage: 2 mV (versus 110 µV)
• Supply Current: 230 µA per channel (versus 1.3 mA per channel)
• Output Current: 75 mA per channel (versus 30 mA per channel)
• Operating Temperature Range: -40°C to 125°C (versus -40°C to 85°C)
• Automotive Grade: AEC-Q100 qualified

The TS912BIDT is suitable for applications where the LMC6482AIMX specifications are met or exceeded. The lower supply current and higher output current capability may provide advantages in power-constrained or high-load-current applications. The extended temperature range and automotive qualification are applicable for automotive and industrial environments. Product status is Active with higher inventory availability (58,220 units).

Frequently Asked Questions (FAQ)

Q: Can LMC6482AIMX/NOPB be used as a direct replacement for LMC6482AIMX?

A: Yes. LMC6482AIMX/NOPB is electrically and mechanically identical to LMC6482AIMX. The difference is packaging format (Cut Tape & Digi-Reel versus standard packaging). Both are 8-SOIC surface mount devices with identical electrical specifications.

Q: What are the key differences between LMC6482AIMX and TS912BIDT?

A: Both devices are dual-channel CMOS rail-to-rail amplifiers in 8-SOIC packages. The TS912BIDT has lower supply current (230 µA vs. 1.3 mA per channel), higher output current capability (75 mA vs. 30 mA per channel), extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C), and AEC-Q100 automotive qualification. Input offset voltage is higher (2 mV vs. 110 µV) and input bias current is higher (1 pA vs. 0.02 pA).

Q: Is TS912BIDT suitable for all LMC6482AIMX applications?

A: TS912BIDT is suitable for applications where the electrical performance envelope of the LMC6482AIMX is met or exceeded. Applications requiring input offset voltage below 2 mV or input bias current below 1 pA should retain the LMC6482AIMX or LMC6482AIMX/NOPB. Applications requiring output current above 30 mA per channel benefit from TS912BIDT selection.

Q: Are all three parts RoHS3 compliant?

A: Yes. LMC6482AIMX, LMC6482AIMX/NOPB, and TS912BIDT are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the significance of the Last Time Buy status for LMC6482AIMX?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. LMC6482AIMX/NOPB (Active status) and TS912BIDT (Active status) are recommended for new designs and ongoing production to ensure long-term supply continuity.

Q: Can the parts be used interchangeably on the same PCB?

A: Yes. All three parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging and pinout, allowing direct PCB substitution without layout modification.

Q: Which substitute is recommended for automotive applications?

A: TS912BIDT is qualified to AEC-Q100 automotive standards with extended operating temperature range (-40°C to 125°C), making it suitable for automotive environments. LMC6482AIMX/NOPB is suitable for industrial and commercial applications within the -40°C to 85°C temperature range.
