Quad JFET op-amp for harsh-environment signal chains
It delivers a 20 V/µs slew rate and 4 MHz -3 dB bandwidth, with an input bias current of 10 pA and input offset voltage of 300 µV. The amplifier operates from a single or dual supply spanning 9 V to 36 V total, and each of the four channels can source or sink 25 mA.
The 20 V/µs slew rate means this amplifier can track a 10 V peak-to-peak sine wave up to about 318 kHz before slew-rate limiting becomes a concern — practical for fast-settling multiplexed data-acquisition front ends, sample-and-hold drivers, and active filters in the low-MHz range. The 4 MHz -3 dB bandwidth supports unity-gain stable operation across the full temperature range. With a supply current of 10 mA total for all four amplifiers, it balances dynamic performance against power dissipation in a sealed module.
Hermetic 14-CERDIP — the package that decides the deployment
The 14-CERDIP (ceramic dual-in-line) package provides a hermetic seal against moisture and contaminants, which is why this part carries the /883B suffix — it is the version qualified for high-reliability and defense/aerospace programs. The through-hole mounting suits legacy board layouts, prototyping, and applications where vibration resistance from a soldered lead is preferred over a surface-mount footprint.
It is listed as RoHS non-compliant, which is expected for a hermetic ceramic package — the lead finish is typically tin/lead solder (SnPb) for high-reliability solder joints.
