  • Description

    The NJMOP277 (Single) / NJMOP2277 (Dual) are high precision operational amplifiers featuring low offset voltage drift of top-class , low offset voltage and low noise and high voltage gain. The NJMOP277 / NJMOP2277 excellent electrical characteristics are guaranteed over a wide operating range (-40°C to +125°C, ±5V to ±15V). Therefore, it is most suitable for measuring instruments that require stability against ambient temperature change and/or for applications such as configuring high gain circuits to process very small signals. Moreover, they have the advantage very small package and high RF noise immunity. It is easy to replacement from defact standard precision operational amplifier: OP-177 series and to design against RF immunity, too.
