Parametric fit for the signal chain
The PM1008AZ is a single-channel general-purpose op-amp in a hermetic 8-CERDIP package, rated for the full military temperature range of -55°C to 125°C. With a gain-bandwidth product of 500 kHz and a slew rate of 0.2 V/µs, it handles low-frequency conditioning loops — sensor buffering, active filtering below 50 kHz, or reference scaling — where the signal does not demand fast edge rates. Supply span runs from 4 V to 40 V single or split, so it can sit on a ±15 V rail common in industrial analog front-ends or a single 5 V logic supply. Input offset voltage is trimmed to 40 µV typical, and input bias current is 40 pA typical — both low enough that the error budget in a precision DC loop is dominated by the external resistor divider, not the amplifier.
Package and mounting — 8-CERDIP considerations
The 8-CERDIP (0.300-inch body, 7.62 mm width) is a ceramic dual-in-line package with a hermetic seal. Through-hole mounting means it inserts into a standard 8-pin DIP socket or solders directly into plated-through holes on a 0.100-inch pitch layout. The ceramic body handles the -55°C to 125°C range without the moisture absorption risk of plastic — relevant for avionics, downhole, or vacuum systems where outgassing matters. The supplier device package is listed as 8-CERDIP, identical to the package/case field. No exposed thermal pad — heat conducts through the leads and the ceramic body to the board or socket. For high-ambient operation near 125°C, forced airflow or a heat-sink clip on the package body helps keep junction temperature within limits.
Lifecycle and compliance
Because it is Active, it is available through authorized distribution channels. No last-time-buy or phase-out schedule has been published. The hermetic package and military temp grade mean it is specified into defense, aerospace, and industrial designs that require a known long-term supply commitment.
