14-pin CERDIP — hermetic, through-hole, RoHS-exempt
The AD5539JQ is a single-channel general-purpose op-amp from Analog Devices, packaged in a 14-lead CERDIP (0.300" body) with through-hole mounting. The hermetic ceramic package suits environments where moisture resistance or high-temperature storage is required, and the through-hole format keeps it compatible with socketed or legacy PCB layouts.
With a slew rate of 600 V/µs and a gain-bandwidth product of 1.4 GHz, this amplifier is built for high-speed pulse amplification, video distribution, or RF front-end stages where settling time and large-signal bandwidth matter.
Supply range and input offset — 9 V to 20 V, 2 mV max
The supply span runs from 9 V minimum to 20 V maximum, allowing operation on ±5 V to ±10 V dual rails or a single 12 V or 15 V rail. Input offset voltage is specified at 2 mV, and input bias current at 6 µA — both typical for a high-speed bipolar input stage. These numbers are not precision-grade, so the part is better suited to AC-coupled or closed-loop gain stages than DC-accurate instrumentation paths.
Active lifecycle, RoHS non-compliant — sourcing notes
However, it is marked RoHS non-compliant — the hermetic CERDIP package uses lead-based solder seals or tin-lead plating, which exempts it from RoHS restrictions in many military, aerospace, and medical applications but blocks it from EU RoHS-compliant BOMs.
