Engineering Selection Recommendations

LMC6482AIMX/NOPB (Texas Instruments)

The LMC6482AIMX/NOPB is the direct equivalent to the LMC6482AIM. This part maintains identical electrical specifications across all critical parameters and is supplied in Cut Tape (CT) & Digi-Reel® packaging. The LMC6482AIMX/NOPB holds Active product status with 65,200 units in stock, providing immediate procurement availability. This part is the primary recommendation for direct replacement in new designs and production continuations. Both parts share the same base product number (LMC6482) and are fully compatible at the functional and mechanical level.

TS912BIDT (STMicroelectronics)

The TS912BIDT is a functionally compatible substitute that meets all mandatory parameter requirements. This device demonstrates superior performance in several areas: lower minimum supply voltage (2.7 V vs. 3 V), higher maximum supply voltage (16 V vs. 15.5 V), extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C), and higher output current per channel (75 mA vs. 30 mA). The TS912BIDT includes automotive-grade qualification (AEC-Q100) and is supplied in Cut Tape (CT) & Digi-Reel® packaging with 58,220 units in stock. This part is suitable for applications requiring extended temperature operation or higher output drive capability. The TS912BIDT exhibits higher input offset voltage (2 mV vs. 110 µV) and input bias current (1 pA vs. 0.02 pA), which may impact precision analog applications requiring ultra-low offset specifications.

Both substitute parts are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and are available in identical 8-SOIC surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can the LMC6482AIMX/NOPB be used as a direct replacement for the LMC6482AIM?

A: Yes. The LMC6482AIMX/NOPB is electrically and mechanically identical to the LMC6482AIM. The primary difference is packaging format: the LMC6482AIM is supplied in Tube packaging, while the LMC6482AIMX/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts share the same base product number and specifications. The /NOPB suffix indicates lead-free, RoHS-compliant construction.

Q: What are the key differences between the LMC6482AIM and TS912BIDT?

A: Both devices are dual-channel CMOS rail-to-rail amplifiers in 8-SOIC packaging. The TS912BIDT offers wider supply voltage range (2.7 V to 16 V vs. 3 V to 15.5 V), extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C), higher output current (75 mA vs. 30 mA per channel), and lower supply current (230 µA vs. 1.3 mA). The LMC6482AIM provides superior input characteristics with lower input offset voltage (110 µV vs. 2 mV) and lower input bias current (0.02 pA vs. 1 pA). The TS912BIDT includes automotive-grade qualification.

Q: Is the TS912BIDT suitable for precision analog applications?

A: The TS912BIDT meets the mandatory functional requirements for dual-channel CMOS rail-to-rail amplification. However, applications requiring ultra-low input offset voltage and input bias current specifications should prioritize the LMC6482AIM or LMC6482AIMX/NOPB, which provide superior precision characteristics (110 µV offset vs. 2 mV, and 0.02 pA bias current vs. 1 pA).

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts—LMC6482AIM, LMC6482AIMX/NOPB, and TS912BIDT—use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging. PCB footprints and land patterns are interchangeable. Pin assignments and functional pinout are identical across all three devices.

Q: What is the significance of the Last Time Buy status for the LMC6482AIM?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the LMC6482AIM. Existing inventory will be depleted without replenishment. For new designs and long-term production requirements, transition to the LMC6482AIMX/NOPB (Active status, same specifications) or TS912BIDT (Active status, enhanced performance) is necessary to ensure supply chain continuity.

Q: Are all three parts RoHS compliant?

A: Yes. The LMC6482AIM, LMC6482AIMX/NOPB, and TS912BIDT are all ROHS3 compliant. All three parts carry Moisture Sensitivity Level 1 (Unlimited) rating and are suitable for standard PCB assembly processes without special handling requirements.

Q: Which part should be selected for automotive applications?

A: The TS912BIDT is qualified to AEC-Q100 automotive standards and is specifically designed for automotive-grade applications. The LMC6482AIM and LMC6482AIMX/NOPB do not carry automotive qualification. If automotive-grade certification is a design requirement, the TS912BIDT is the appropriate selection.
