NJM2143 Series
Single-Supply Dual Operational Amplifier

Download Datasheet

  • Description

    The NJM2143 is a single-supply dual operational amplifier in small packages. It offers a low voltage operation from 3V and low operating current of 0.7mA(typ.). There is no crossover distortion in single supply operation, because the load is directly coupled to the ground. And in dual supply operation, by connecting a pull-down resister between output and negative supply V- terminals the crossover distortion can be reduced. The NJM2143 is available in both 8-lead MSOP and thin type MSOP packages.
