Four CMOS op-amps that sip power — the LMC6464BIM
The 50 kHz gain-bandwidth product and 0.028 V/µs slew rate tell you this is a low-frequency part — think DC offsets, thermocouple amplifiers, or photodiode transimpedance stages, not audio or motor drive.
Package and mounting
The LMC6464BIM draws 90 µA total for all four amplifiers — that's 22.5 µA per channel. If you're designing a multi-channel data logger that runs for a year on a coin cell, this is the kind of budget you work with. The 0.15 pA input bias current (typical) means you can hang a 10 MΩ source resistor off the input and still see negligible offset drift.
It's not a mil-spec part, but it's fine for most industrial control and automotive cabin applications.
Active lifecycle, but watch the RoHS flag
The catch: it's RoHS non-compliant, meaning it uses a tin-lead (SnPb) finish. If your assembly line is RoHS-only or requires Pb-free reflow profiles, this part won't pass. For legacy repairs, mil-spec builds, or any line that still runs SnPb, it's a clean fit.
Bulk packaging — what you get
That's fine for bench repairs, prototype runs, or low-volume production where you're hand-placing or using a pick-and-place with tube feeders.
