Dual CMOS op-amp for precision signal conditioning
The LMC662CMX/NOPB: Its 0.002 pA input bias current and 1 mV input offset voltage make it suited for high-impedance sensor interfaces, photodiode amplifiers, and low-frequency active filters where DC accuracy and minimal loading are critical. The rail-to-rail output stage maximizes dynamic range at low supply voltages, and each channel can source or sink 40 mA.
Supply and temperature — what drives the BOM fit
The supply span from 4.75 V to 15.5 V covers both single 5 V and 12 V rails as well as split supplies like ±5 V. For designs that need industrial or automotive temperature reach, a different grade would be required.
Lifecycle and sourcing posture
The date-code and marking consistency should trace cleanly back to the authorized chain — the laser etch is a fingerprint worth verifying on any non-franchise channel.
Package and footprint considerations
The 8-SOIC footprint matches standard SOIC-8 land patterns, simplifying PCB layout.
