Quad op-amp for multi-channel signal chains
The AD8694ARZ-REEL7 from Analog Devices is a quad general-purpose op-amp with rail-to-rail output, packing four amplifiers into a 14-SOIC package. It delivers a 10 MHz gain-bandwidth product and a 5 V/µs slew rate, drawing just 950 µA total supply current across all four channels. The part operates from a single 2.7 V to 6 V supply and is specified over the -40°C to 125°C industrial temperature range, making it a fit for multi-channel sensor conditioning, ADC drivers, and active filters in equipment that sees under-hood or outdoor temperature extremes.
Rail-to-rail output and input bias current
Rail-to-rail output swing lets each channel drive close to the supply rails. The 1 pA input bias current suits high-impedance sources like photodiodes or pH probes.
Supply current and output drive
At 950 µA total supply for all four amplifiers, this part keeps the power budget tight in multi-channel data-acquisition boards. Each channel can source or sink 80 mA.
