Quad JFET op-amp in a hermetic 14-CDIP — built for extreme environments
The 5962-9080902MCA is a quad JFET-input operational amplifier from the standard military/aerospace drawing system, packaged in a 14-lead ceramic DIP (14-CDIP) with through-hole mounting.
Package and thermal — ceramic DIP that survives rework and the board
No exposed pad to worry about, no underfill. The through-hole mounting means it sits mechanically locked into the board — good for vibration environments. Just watch the lead forming if you're hand-inserting into an existing board; the leads are stiff and can crack a solder joint if bent more than once.
The 2 MHz gain-bandwidth product and 3.4 V/µs slew rate place this op-amp in the general-purpose precision band — adequate for audio-frequency filtering, slow servo loops, and sensor conditioning up to a few hundred kHz. The 4 pA input bias current is the standout feature: with a JFET front end, you can interface directly to a photodiode or a high-impedance bridge without adding a buffer stage. Output current capability of 80 mA per channel is generous for a quad op-amp, enough to drive a modest cable or a small relay coil directly. The 900 µV input offset voltage is typical for a JFET design at this price and reliability tier — not a precision auto-zero grade, but fine for most industrial and aerospace analog processing.
