Quad CMOS op-amp for precision multi-channel signal chains
The OP496GSZ-REEL7 is a quad CMOS operational amplifier from Analog Devices, packing four independent rail-to-rail output amplifiers into a single 14-SOIC (0.154", 3.90 mm width) surface-mount package. With a gain bandwidth product of 450 kHz and a slew rate of 0.3 V/µs, this part is built for low-frequency precision tasks — sensor conditioning, instrumentation amplifiers, and multi-channel data acquisition front-ends where DC accuracy matters more than raw speed. The CMOS input stage delivers a typical input bias current of just 10 nA and an input offset voltage of 35 µV, keeping errors low when interfacing with high-impedance sources like thermocouples, strain gauges, or photodiodes. The supply span runs from 3 V to 12 V, so it works on a single 3.3 V or 5 V rail as easily as a 12 V industrial bus.
Industrial temperature grade and supply flexibility
Rated for operation from -40°C to 125°C, the OP496GSZ-REEL7 covers the full industrial temperature envelope — suitable for outdoor telecom cabinets, engine-bay electronics, and factory-floor sensor modules that see thermal cycling. Rail-to-rail output swing maximizes the dynamic range on low supply voltages, critical when the ADC reference is the same 3.3 V rail. Each output channel can source or sink 4 mA, enough to drive the input of a successive-approximation ADC or a downstream comparator without an additional buffer stage. The 10 nA input bias stays low across temperature, preserving accuracy in multi-channel multiplexed systems where the source impedance varies channel to channel.
