1. TLC2272AIDR Substitution Conclusion From an electrical performance perspective, the TLC2272AIDR can be considered a conditional substitute for the LMC6082AIM/NOPB. Both are dual CMOS operational amplifiers from TI, offered in 8‑SOIC packages with rail‑to‑rail output, and their supply voltage ranges are highly overlapping (~4.5 V to 16 V). The key differences lie in the following: the TLC2272AIDR exhibits an input bias current (1 pA) two orders of magnitude higher than that of the LMC6082 (0.01 pA), its input offset voltage (300 µV) is double that of the latter, and its quiescent current (2.4 mA) is significantly greater. In applications sensitive to input errors and power consumption—such as high‑impedance sensor signal conditioning or precision DC amplification—substitution may lead to degraded accuracy and poorer power efficiency. However, the TLC2272AIDR offers superior gain‑bandwidth product (2.25 MHz) and slew rate (3.6 V/µs) compared to the LMC6082 (1.3 MHz, 1.5 V/µs), along with stronger output current capability (50 mA). In scenarios requiring higher speed and greater load‑driving capacity—for instance, audio buffering or intermediate‑frequency signal processing—the TLC2272AIDR may actually present an advantage.
