5 MHz JFET op-amp in a hermetic can
The LF256H/NOPB: The supply span runs from 10 V to 44 V. Supply current is 5 mA typical.
TO-99-8 — the package that changes the sourcing decision
This part comes in a TO-99-8 metal can with through-hole mounting. That hermetic metal package is a different world from the plastic SOIC or MSOP packages of modern JFET op-amps like the TLV9351IDCKR or TLV9362IDDFR. The metal can also handles higher junction-to-ambient thermal mass than a small plastic SMD package, which matters if the op-amp sits near a heat source on a dense board.
