Fast JFET op-amp in a hermetic can
It operates from a 9 V to 36 V supply span and draws 3.5 mA quiescent current. The 30 pA input bias current and 250 µV input offset voltage suit precision signal conditioning in high-impedance sensor interfaces.
The 75 V/µs slew rate is the standout rating on this part. For comparison, the AD712KNZ and AD711JRZ-REEL7 — both JFET op-amps — are spec'd at 20 V/µs. The AD744TH's higher slew rate supports faster settling and larger signal swings at higher frequencies, which matters in waveform generation, fast ADC drivers, or pulse-processing front-ends where the slower sibling would introduce slew-induced distortion.
Package and temperature grade — deployment reality
The TO-99-8 metal can is a through-hole package. It is not a surface-mount footprint, so it requires board holes and manual or wave-solder assembly. The metal can provides a hermetic seal and better thermal dissipation than plastic DIP or SOIC packages.
It is RoHS non-compliant, so verify your assembly's RoHS exemption or accept the non-compliant status for high-reliability / military contracts where lead-bearing solder is still permitted.
