Active dual JFET op-amp for precision signal chains
The OP285GSZ-REEL7 is an active dual JFET-input operational amplifier from Analog Devices, combining a 9 MHz gain-bandwidth product with a 22 V/µs slew rate in the standard 8-SOIC footprint. The JFET input stage delivers 100 nA input bias current and 35 µV input offset voltage, suiting it for precision analog front-ends where low drift and high input impedance matter.
Operating from a 9 V to 44 V supply span, the part works across single-supply and dual-supply rails without needing a separate low-voltage regulator. Each amplifier draws 4 mA supply current — the dual-channel package keeps the total quiescent load under 8 mA for the pair.
