What the 40 V supply span and 3 nA bias mean for your BOM
The OP12CZ/883C is a single-channel general-purpose op-amp in a hermetically sealed 8-CERDIP package, rated for a 40 V supply span — the full rail-to-rail voltage between V+ and V- — so it runs on standard ±15 V or ±20 V industrial supplies without needing a secondary regulator. Input bias current is 3 nA typical, and input offset voltage is 350 µV — both figures are moderate for a general-purpose amplifier but sufficient for DC-coupled signal conditioning where the source impedance stays below 100 kΩ; above that the bias current drop across the source resistance starts to dominate the offset error.
Package, mounting, and board-fit checklist
8-pin CERDIP (0.300-inch body width) with through-hole leads — the ceramic body resists moisture absorption and thermal shock better than plastic DIP, so it survives the solder wave without the pre-bake that a plastic DIP of the same MSL would need. The 0.100-inch pitch and 7.62 mm row spacing match the standard DIP-8 footprint; no board spin is required if the existing layout already accepts a plastic DIP-8 — just confirm the CERDIP's 0.015-inch thicker body clears the adjacent components.
