Dual CMOS op-amp for precision signal conditioning
Its CMOS input stage keeps input bias current at 0.002 pA, making it suitable for high-impedance sensor interfaces such as photodiode amplifiers and pH probe buffers. The push-pull rail-to-rail output stage swings within millivolts of each supply rail, preserving dynamic range in single-supply designs from 4.75 V to 15.5 V. Each channel can source or sink 40 mA, enough to drive ADC inputs or modest loads directly.
The LMC662AIMX operates from a single supply spanning 4.75 V to 15.5 V, or split supplies up to ±7.75 V. Total quiescent current for both amplifiers is 750 µA, which keeps the thermal budget low in densely populated boards.
Package and footprint
The supplier device package is 8-SOIC. The listed shipping medium is Bulk, so verify the required reel or tube quantity when planning the kitting BOM.
Lifecycle and compliance
It is listed as RoHS non-compliant, which matters for designs targeting EU RoHS exemptions or legacy assemblies that require tin-lead solder. For new designs requiring RoHS compliance, check the LMC662AIMX/NOPB variant or a functionally similar CMOS dual op-amp in the same package.
