15 V/µs slew rate, TO-99-8 metal can — the field-swappable JFET op-amp
It delivers a 3 MHz gain-bandwidth product and a 15 V/µs slew rate, drawing 2 mA supply current. The JFET input stage keeps input bias current at 50 pA, making it suitable for high-impedance sensor interfaces, integrators, and sample-and-hold circuits. The metal can is socketable and field-replaceable — no hot-air station needed, just a DIP socket and a pair of pliers.
RoHS non-compliant — plan for it
However, it is RoHS non-compliant. That means lead-bearing solder terminals on the TO-99-8 can. For new designs that must meet EU RoHS or similar green directives, you will need an exemption or a drop-in surface-mount alternative. The through-hole package is exempt from some RoHS requirements in certain applications (military, aerospace, high-rel), but verify your own compliance scope.
Why the TO-99-8 package still matters
The TO-99-8 metal can is hermetic, which gives it an edge in humid or corrosive environments where plastic SOIC packages can delaminate. It also handles repeated soldering and desoldering better than surface-mount parts — useful for prototyping, rework, or field upgrades. The through-hole mounting means it can be socketed, so swapping it on site with what is in the kit is straightforward. No lab bench required.
