The OPA348AIDBVR is a low-power operational amplifier (op-amp) used in a variety of applications. It typically operates from a single or dual supply voltage. Operational amplifiers work by amplifying the difference between the voltages at the non-inverting input (+) and the inverting input (−). It is designed for low noise, low distortion, and high precision. The op-amp can be used in configurations such as voltage followers, inverting amplifiers, non-inverting amplifiers, and filters . The power supply should be in the range of 2.7V to 40V for dual supplies and 1.8V to 40V for single-supply configurations.FAQ for OPA348AIDBVR
