Engineering Selection Recommendations

LMC6482IMX/NOPB (Direct Equivalent)

The LMC6482IMX/NOPB is the direct equivalent of the LMC6482IMX, manufactured by Texas Instruments with identical electrical specifications and package configuration. This part is currently in Active product status with higher inventory availability (35,600 units). The /NOPB designation indicates lead-free, RoHS-compliant packaging. This substitute provides seamless design compatibility with zero performance deviation and is the preferred replacement for end-of-life mitigation of the LMC6482IMX.

TS912AIDT (CMOS Alternative)

The TS912AIDT, manufactured by STMicroelectronics, is a CMOS dual-channel amplifier in 8-SOIC package with Active product status. This device maintains equivalent slew rate (1.3 V/µs) and comparable gain bandwidth product (1.4 MHz). The TS912AIDT offers extended operating temperature range (-40°C to 125°C) and lower supply current (230 µA vs. 1.3 mA), providing improved thermal performance and power efficiency. The device includes AEC-Q100 automotive qualification. Supply voltage span extends to 16 V maximum, exceeding the LMC6482IMX specification. Input offset voltage is significantly lower (5 mV vs. 110 µV), and output current capability is higher (75 mA vs. 30 mA per channel). This substitute is suitable for applications requiring enhanced temperature performance and reduced power consumption.

MC33202DR2G (General Purpose Alternative)

The MC33202DR2G, manufactured by onsemi, is a general-purpose dual-channel amplifier in 8-SOIC package with Active product status. This device provides higher gain bandwidth product (2.2 MHz) and greater output current capability (80 mA per channel). The MC33202DR2G operates across a wider supply voltage range (1.8 V to 12 V minimum to maximum). Input bias current is significantly higher (80 nA vs. 0.02 pA), and slew rate is lower (1 V/µs vs. 1.3 V/µs). Operating temperature range extends to 105°C. This substitute is applicable to applications where higher bandwidth and output drive capability are beneficial, and where the lower input bias current specification of the LMC6482IMX is not a critical design constraint.
