30 µV offset, 80 pA bias — precision DC performance in a hermetic package
Its 30 µV input offset voltage and 80 pA input bias current make it a natural fit for sensor signal conditioning, instrumentation front-ends, and industrial control loops where drift and offset matter more than bandwidth. The 0.15 V/µs slew rate confirms this is a low-frequency part — think strain-gauge amplifiers, thermocouple buffers, or precision integrators, not video or fast ADC drivers. The supply span runs from 4 V to 36 V, so it works on a single 5 V rail or a ±15 V industrial supply without a separate regulator.
8-CERDIP — hermetic, through-hole, rework-friendly
The AD705AQ comes in an 8-pin CERDIP (0.300" wide, 7.62 mm body) — a hermetic ceramic package with a glass seal. This is the package you want when the board lives in a humid, condensing, or high-vibration environment where plastic SOIC packages risk moisture ingress or cracked epoxy. Through-hole mounting means it survives hot-air rework cycles well: the leads are robust, and the ceramic body doesn't absorb moisture the way a plastic MSL 3 part does. Because it's RoHS non-compliant (the leads are tin-lead solder dipped), this part is exempt from RoHS restrictions in many military, aerospace, and medical legacy designs. If your BOM requires full RoHS compliance, you'll need a lead-free alternative — but for high-reliability rework and repair, the tin-lead finish is actually preferred for its wetting and fatigue resistance.
Sourcing and fit — what to check before ordering
The 4 V to 36 V supply range and 30 µV offset cover the majority of industrial sensor interface designs. The 0.15 V/µs slew rate means you won't use this for high-speed loops — but for DC accuracy, it's the right choice. No stock or price figures are published here — submit an RFQ for a firm quote.
