Parametric profile and board-fit
The LM201AH/NOPB: Input offset voltage is 700 µV typical, input bias current 30 nA, and supply current 1.8 mA — the bias current matters for high-impedance sources above 100 kΩ where the voltage drop across the source resistance becomes significant. Runs on a 10 V to 44 V total supply span, covering common single-rail and split-rail configurations (±5 V to ±22 V).
Package and procurement posture
Housed in a TO-99-8 metal can (through-hole) — the hermetic metal package provides better shielding and thermal dissipation than plastic DIP or SOIC, and the 8-lead circular pinout mates with standard TO-99 sockets. Supplied in bulk, not tape-and-reel.
