Many single-supply operational amplifiers are capable of rail-to-rail input operation, if they have the proper input circuitry to support this function. This article is an expansion of the blog post ...

National Semiconductor has developed a proprietary silicon-on-insulator (SOI) BiCMOS analog process technology specifically for operational amplifier applications in the 0.9 V to 12 V supply voltage ...

Current differencing transconductance amplifiers (CDTAs) provide a versatile platform for signal processing in contemporary integrated circuits. By converting differential input currents into ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

Zero-drift amplifiers dynamically correct their offset voltage and reshape noise density. Two commonly used types—auto-zero amplifiers and choppers—achieve nanovolt-level offsets and extremely low ...
