LMC6484 is an Ultra-low Bias Current, Precision CMOS Rail-to-Rail Input and Output Quad Operational Amplifier IC. LMC6484 device provides a common-mode range that extends to both supply rails. This rail-to-rail performance combined with excellent accuracy, due to a high CMRR, makes this device unique among rail-to-rail input amplifiers. LMC6484 offers a wide variety of features such as Excellent CMRR and PSRR, high noise immunity, and low power dissipation.
Operational Amplifier
An operational amplifier or op-amp is simply an electronic linear Integrated Circuit or IC that has multiple terminals. An op-amp is a voltage amplifying device that is meant to be work with external feedback components such as resistors and capacitors. Operational amplifiers are considered to be one of the most vastly used electronic component, with applications ranging from small scale consumer electronic components such as smartphones, tablets, PCs, to large scale industrial instrumentation tools such as poisonous gas sensors and transducers for impurity detection.
