What the GS8331 does
The GS8331/8332/8334 family comprises single, dual, and quad zero-drift CMOS operational amplifiers featuring rail-to-rail inputs and outputs. These devices operate on a single supply from 1.8V to 5.5V, offering a 350 kHz gain-bandwidth product, 25 µA quiescent current per amplifier, and 20 pA input bias current. The parts maintain a maximum offset voltage of 10 µV and a drift of 0.01 µV/°C. Engineers typically select these amplifiers for transducer applications, handheld test equipment, temperature measurements, battery-powered instrumentation, and electronics scales where low power and high impedance are critical.
