■ GENERAL 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.
