Hermetic general-purpose op-amp for extended-range designs
The OP12FJ is a single-circuit general-purpose operational amplifier in a TO-99-8 metal can package through-hole mounted. Input bias current is 3 nA typical, input offset voltage 350 µV, and the supply span runs from 40 V minimum to 40 V maximum — a single-rail or split-rail design at ±20 V, providing headroom for large-signal swings in precision analog front-ends.
Package, compliance, and lifecycle
The TO-99-8 metal can is a hermetic package — the metal-to-glass seal keeps moisture and contaminants out, which is why it remains common in high-reliability and defense programs. Through-hole mounting requires a drilled PCB with plated holes; the can body is typically socketed or soldered directly. Supplied in bulk packaging (loose units, not tape-and-reel), consistent with low-volume or prototype quantities typical of through-hole hermetic op-amps.
