The 0.002 pA input bias current is orders of magnitude lower than a general-purpose bipolar op-amp. That means you can skip a separate JFET buffer stage in a transimpedance amplifier or a high-impedance divider.
A close functional peer is the OPA4374AIPWT from TI — also a quad CMOS rail-to-rail op-amp in a surface-mount package. The OPA4374 offers a higher gain bandwidth of 6.5 MHz and a slew rate of 5 V/µs, but its input bias current is 0.5 pA versus the LMC660's 0.002 pA. For ultra-high-impedance applications, the LMC660AIM/NOPB remains the better fit.
Yes. The supply voltage range is 4.75 V to 15.5 V, and the rail-to-rail output allows full swing on a single supply. It operates from a single 5 V or 12 V rail without a negative supply.
The LMC660AIM/NOPB suffix indicates a lead-free (NOPB) finish, compliant with ROHS3. The LMC660AIM (without /NOPB) is the earlier lead-bearing version. Electrically they are identical.
