Dual op-amp for precision low-frequency signal chains
The AD706JRZ-REEL from Analog Devices is a dual general-purpose operational amplifier in an 8-SOIC surface-mount package, supplied on Tape & Reel. It delivers an 800 kHz gain-bandwidth product and a 0.15 V/µs slew rate, paired with a low 30 µV input offset voltage and 50 pA input bias current. This combination suits it for precision DC amplification, sensor conditioning, and low-frequency active filtering in commercial temperature range (0°C to 70°C) equipment such as instrumentation front-ends, data-acquisition signal chains, and industrial control loops.
Key ratings and what they mean for the BOM
The 0.15 V/µs slew rate and 800 kHz bandwidth tell you this is a low-speed amplifier — it cannot track fast edges above a few hundred kilohertz. That is not a flaw; the part is designed for precision DC and low-frequency AC paths where noise and offset matter more than speed. The 30 µV input offset is the headline precision figure: it eliminates the need for external nulling in many circuits and keeps the error budget tight. Supply span from 4 V to 36 V gives flexibility for single- or dual-supply rails, and the 750 µA supply current per amplifier keeps the thermal load low in dense boards.
