General-purpose op amp in a hermetic ceramic DIP
The PM1008GZ from Analog Devices is a single-channel general-purpose operational amplifier in an 8-pin CERDIP package (8-CDIP, 0.300" width). It offers a 500 kHz gain-bandwidth product with a 0.2 V/µs slew rate, suited for low-to-moderate speed signal conditioning where through-hole mounting is preferred. The 8-CERDIP package provides a hermetic seal, making it a candidate for environments where moisture resistance matters more than the 0°C to 70°C commercial temperature range suggests — think lab instruments or industrial control boards that see condensation during power-down.
Supply range and precision for single-rail or split-rail designs
The amplifier operates from a 4 V to 40 V total supply span, covering both single-supply (e.g., 5 V, 12 V, 24 V) and split-supply (e.g., ±2 V to ±20 V) configurations without needing a separate rail regulator. Input offset voltage is trimmed to 40 µV typical, and input bias current is 40 pA — low enough for high-impedance sensor interfaces like photodiode amplifiers or pH probe buffers where the bias current error term must stay below the signal floor. Quiescent supply current is 380 µA per amplifier, which keeps the thermal budget low in multi-channel boards or battery-powered instruments that spend most of their life in active measurement.
Active production, RoHS non-compliant — plan accordingly
It is marked RoHS non-compliant, which means it contains lead in the solder-dip terminations or die-attach — acceptable under many industrial and military exemptions, but verify your assembly house's policy on lead-bearing parts before committing the BOM line. For new designs requiring RoHS compliance, a functionally similar op amp in a surface-mount package would be needed — the PM1008GZ is best suited for legacy board spins or through-hole-only production where the RoHS exemption applies.
