What the GS8551 does
The GS8551/8552/8554 family comprises single, dual, and quad zero-drift CMOS operational amplifiers featuring rail-to-rail input and output stages. These devices operate on a single supply from 1.8V to 5.5V, delivering a 1.8MHz gain-bandwidth product, 30µV maximum offset voltage, and 20pA typical input bias current. With 180µA quiescent current per amplifier, they excel in low-power applications requiring high impedance. Engineers typically deploy these amplifiers in transducer circuits, handheld test equipment, temperature measurement systems, battery-powered instrumentation, and electronics scales. The series supports extended temperature ranges from -45°C to +125°C and includes an embedded RF anti-EMI filter for superior performance in driving analog-to-digital converters.
