NJU7057RB1 Low Noise, Low Offset Voltage Drift, Rail-to-Rail Output, Excellent EMI Immunity, CMOS Operational Amplifier

The NJU7057 is  Dual rail-to-rail output CMOS operational amplifier.

 

The number of mobile devices increases day by day.

All mobile devices are wireless and radiate electromagnetic waves producing electromagnetic interference with other devices.

EMI causes  degradation in the performance of electrical Equipment.

Low noise of 15nV/√Hz and low offset drift of 0.7µV/°C typ. make them suitable for several sensor amplifiers and preamplifiers. NJU7057  operate from 1.8V to 5.5V supply voltage. They are optimized for 2-cell battery systems and 1-cell Li-ion battery systems. The NJU7057 have high-impedance inputs with ground sensing, rail-to-rail output that swings within 50mV from rail with 10kΩ load at 1.8V supply, 2.1MHz gain bandwidth and 0.8V/μs Slew rate. These characteristics make them excellent performance for general-purpose applications.NJU7057 is offered in 8-pin MSOP (TVSP): meet JEDEC MO-187-DA / thin type package and DFN that is thin and 2mm square small package.
