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

  • Consumer
  • PLP
  • RoHS

The NJU7057 are Dual rail-to-rail output CMOS operational amplifiers. 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): meets JEDEC MO-187-DA / thin type package and DFN that is thin and 2mm square small package.
