■ 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.
