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. This part is designed for precision analog signal conditioning in avionics, missile guidance, satellite telemetry, and downhole instrumentation where the ceramic hermetic seal and wide temperature range are mandatory.
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.
