2. LMV822M Substitution Conclusion The LMV822M shows some parameter similarities to the original MCP6482T-E/SN, but key differences affect its suitability as a substitute: Its input bias current is significantly higher (40 nA vs. 1 pA), resulting in much lower input impedance, which makes it unsuitable for high-impedance or precision measurement applications such as sensor interfaces. The slew rate is slightly lower (2 V/µs vs. 2.7 V/µs), potentially affecting high-speed signal processing, and the supply current is higher (500 µA vs. 240 µA per channel), increasing power dissipation. On the positive side, it provides higher output current (45 mA vs. 12 mA) and a slightly greater gain-bandwidth product (5.6 MHz vs. 4 MHz), supporting stronger drive and wider bandwidth requirements. The higher minimum supply voltage (2.5 V vs. 2.2 V) may also limit use in low-voltage scenarios. Substitution could be considered if the original application is not sensitive to input bias current and can accept moderately higher power consumption, but it is generally not recommended for precision circuits.
